Answer: (-1,4)
Explanation:
y=-2x+2 y=7x+11 <----- substitute this equation for y in the
equation y=-2x+2
7x+11=-2x+2 Add 2x to both sides
9x+11=2 Subtract 11 from both sides
9x=-9 Divide both sides by 9
x=-1
y=-2(-1)+2 Plug in x to one of the equations, I chose y=-2x+2
y=2+2 because it was the easiest, then solve
y=4
Solution is (-1,4)
