Question

Solve the following system of equations using substitution.
y=2x-2
-4x-y=26

Answer 1

simply plug in for y


-4x-(2x-2)=26

-4x-2x+2=26

-6x+2=26

-2

-6x=24

x=-4

now plug in x in either equation, i’ll go with the top one!

2(-4)-2

-8-2

=-10

so y=-10

so the system’s answer is (-4,-10)

hope this helps
