Which of the following is a system of linear equations in two variables?
Simultaneous equations have at least two unknown variables.
What does it mean to solve a system of linear equations?
Find values for each of the unknown variables (or at least as many as is possible for the system) that satisfy all the equations.
Can a system of two linear equations in two variables have 3 solutions?
No. At least, it can't have EXACTLY 3 solutions, if that's what you mean. A system of two linear equations in two variables can have:No solutionOne solutionAn infinite number of solutions
What is -8t - 11x?
It is a linear expression in two variables. As an expression it cannot be solved. Furthermore, to solve equations in two variables you need at least two linear equations.
Translate this word problem as a system of equations and then solve using substitution?
A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.
When you formulate a system of equations you have at least how many factors?
You don't need ANY factor. To find a unique solution, or a few, you would usually need to have as many equations as you have variables.
What is the answer to solve by elimination x plus 2y equals 0?
The answer is that it cannot be done. To solve a set of equations in k variables (in this case, 2) you need at least two independent equations.
Is free variable unique or can we have more than one free variables in linear algebra please elaborate?
You can have any number of free variables. If you have m variables and n linear equations then, if m > n, you will have at least (m - n) free variables.
What is x plus y equals 30?
It is an equation of a straight line. But it is not possible to tell you what x and y equal because you have only given one equation. Since there are two variables (x and y), you need at least 2 equations to solve for x and y. (Likewise if you had 3 variables, you would need at least 3 equations).
-20x plus y equals 52?
To solve for 2 unknown variables you need at least 2 independent equations. You have only 1.
What is the uses of matrices?
Matrices are generally used to solve simultaneous equations. You use the co-efficient of the variables and arrange them in a matrix to solve them. To do so requires at least as many equation as there are variables. Other uses include vector calculations.
How do you solve 5x plus 6y equals -60?
You cannot solve 1 linear equation in 2 unknown variables. You need at least two independent equations.
