x - 3y = 11
So x = 11 + 3y
Then, by the other equation, 4x + 3y = -1
becaomes 4(11+3y) + 3y = -1
or 44 + 12y + 3y = -1
or 15y = -45 so that y = -3
x = 6 and y = -2
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
To solve an equation with three unknowns, x, y and z, you require 3 independent equations.
The question refers to the "following". In such circumstances would it be too much to expect that you make sure that there is something that is following?
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.
How many solutions are there to the following system of equations?2x - y = 2-x + 5y = 3if this is your question,there is ONLY 1 way to solve it.
x = -1.2, y = -3
To solve a system of equations, you need equations (number phrases with equal signs).
The solutions are: x = -2 and y = 4
the answer
To solve for two unknowns (x and y) it is necessary to have two independent equations.
x = 6 and y = -2
Check your text book for how to solve it.
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.
x = 4 and y = 0
If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
