Answer:
(-9, -6)
Explanation:
-2x+8y=-30
9x-16y=15
Start by multiplying the first equation by 2:
-4x+16y=-60
Now, add the two equations to eliminate y:
9x-4x=15-60
5x=-45
Divide both sides by 5
x=-9
Plug -9 in for x to solve for y:
-2(-9)+8y=-30
18+8y=-30
Subtract 18 from both sides
8y=-48
Divide both sides by 8
y=-6
(x,y)=(-9,-6)
