-x+y=-2

4x-4y=8
WHAT ARE THE SOLUTIONS OF THE FOLLOWING SYSTEM?

1 answer

Add x and 2 to both sides of the first equation.

x = y + 2

4x -4y = 8

Substitute y+2 for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
