Answer:

y = -1

x = 9

(9, -1)

Step-by-step explanation:

1) Since "x" equals -4y+5, substitute that into the bottom equation for x: -4y+5+2y=7

2) Combine like terms: -2y+5=7

3) Subtract 5 from both sides: -2y=-2

4) Divide both sides by -2: y=-1

Now you have figured out that y= -1

1) Substitute -1 for y in the top equation: x=-4(-1)+5

2) Solve: x=4+5

3) x=9

Now you have figured out that x=9

The final answer is (9, -1)

Hope this helps! :)
