Answer:
Is one of them supposed to by x?
Step-by-step explanation:
6x- y = 11
-4x + 5y = 8
With a system of equations, you need to solve for one variable first and the substitute to find the other variables. y is easier to solve for.
6x - y =11 Subtract 6x to both sides.
-y = -6x +11 Multiply by -1 on both sides
y = 6x - 11
We now subsitute y with 6x - 11 in the other equation.
-4x + 5y = 8
-4x + 5(6x-11) = 8
-4x +30x -55 =8
26x = 63
x = 63/26
and now we subsitute this to solve for actual y.
y= 6x -11
y= 6*(63/26)-11
