get the x or y on the top then substitute on the bottom equation [lets do x] : 5x = -4y + 2 (moved the 4y)
(5x)/5 = (-4y+2)/5 (divide 5 to get x alone)
x = (-4y+2)/5 theres ur x now substitute on the bottom
-5[(-4y+2)/5] – 2y = 4 Solve then you get your y
*He said substitution not elimination

Do elimination. Add the two together to get x or y by itself.
5x+4y=2
-5x-2y=4
2y=6
y=3
Then, plug y back into one of the original equations
5x+12=2
5x=-10
x=-2
The final answers are x=-2 y=3
