Step-by-step explanation:

$\left \{ {{-8x+7y=-5} \atop {-4x+8y=20}} \right.$

$\left \{ {{-64x+56y=-40} \atop {28x-56y=-140}} \right.$ <-- Multiply top by 8 and bottom by -7 so y can be cancelled out

-36x=-180

x=5

-4x+8y=20

-4(5)+8y=20

-20+8y=20

8y=40

y=5

Therefore, the solution to the system of equations is (5,5)
