Can I and how would I solve 5x 6y-23 and 2x-5y13 (system of equations) without using a calculator?
Without any equality signs and not knowing some of the minus or plus values of the given terms we can't considered it to be a system of simultaneous equations but if you meant: 5x+6y = -23 and 2x-5y = 13 then by multiplication, elimination and substitution the values of x and y work out as x = -1 and y = -3
When solving systems of linear equation's when would you get no solution as an answer?
You get no solution if the lines representing the graphs of both equations have the same slope, i.e. they're parallel. "No solution" is NOT an answer.
Does the graph of a system of equations with different slopes have no solutions?
The graph of a system of equations with the same slope will have no solution, unless they have the same y intercept, which would give them infinitely many solutions. Different slopes means that there is one solution.
If a system of equation is inconsistent that means that the graphs of the two equations do not have any points in common what types of lines would be the result of an inconsistent system of equations?
In two dimensions, parallel ones. In three dimensions, either parallel or skew ones.
How would you know that your equation has no solutions without actually solving it?
It really depends on the type of equation. Sometimes you can know, from experience with similar equations. But in many cases, you have to actually do the work of trying to solve the equation.
When using elimination to solve a system of equations how would you recognize it has no solution?
If in the course of your elimination you come across a clearly untrue statement such as 0 = 2, it indicates that there is no solution. For example, let's pick a simple system. x = 9 x = 0 If we use elimination by multiplying the bottom equation by -1 to eliminate the x's then add the two equations together, we will end up with 0 = 9 which is clearly an untrue statement. Therefore the two equations (actually parallel lines) have no solution.
What would you need to help you with it comes to solving equations?
When solving equations remember that whatever operations are performed on the LHS of the equation must be performed on its RHS to keep the equation in balance.
Which method would be best for solving the system x 8y plus 5 and 3x - 2y 11?
If you mean: x = 8y+5 and 3x-2y = 11 then the simultaneous equations can be solved by a process of elimination. -------------------- Since the first equation is solved for x, substitution should be easy. There is no "right" answer to this question - it depends on your taste and experience.
Solve linear equations with complex coefficients on both sides?
You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.
What are the answers to the math paper called solving equations with negative variables?
We do not do your homework for you because that would be cheating.
What is an ordered pair that makes all equations in a system true?
That would be the "solution" to the set of equations.
Can any of these steps be eliminated solving rational equations?
would you add any steps to make it easier or to make it easier to understand
What is the answer to the systems of equations 2x plus y equals 6 6x plus 3y equals 18?
2x + y = 66x + 3y = 18Usually you can use elimination, substitution, graphing, matrices, etc. to find the answer to this system. If you use any of these methods (elimination and graphing in particular) you will see that these two equations are actually the same: multiply the first equation by three and you will see what I mean.So picture it: graphing this system would essentially be drawing the same line twice. The two lines always overlap, so the equations share infinite solutions. Therefore the solution to the system is the whole line, or all the (x, y) points that satisfy 2x + y = 6.
Solve this system of equations using the addition method x plus y equals 6?
When talking about a "system of equations", you would normally expect to have two or more equations. It is quite common to have as many equations as you have variables, so in this case you should have two equations.
How do you solve a system of equation with 3 equations and 3 variables?
If you know matrix algebra, the process is simply to find the inverse for the matrix of coefficients and apply that to the vector of answers. If you don't: You solve these in the same way as you would solve a pair of simultaneous linear equations in two unknowns - either by substitution or elimination. For example, change the subject of one of the equations to express one of the variables in terms of the other two. Substitute this value into the other two equations. When simplified, you will have two linear equations in two variables.
What would be a solution to a system?
The solution would be the point of intersection of the graphical representation of all equations within the system.
What is X for Chemthink Ionic Formulas?
X would be the metal in Ionic Formulas. These equations you will be solving for X and X alone every time.
