Answer: x= -2

               y=4

Step-by-step explanation:

-5x+3y=22   I

8x-2y=-24    II

-------------------------

From second equation exp. y and return it in to first equation

y=(24+8x)/2

y=12+4x

-5x+3(12+4x)=22

-5x+36+12x=22

7x=-14

x= -2

y=12+4*(-2)

y=12-8

y=4

Simplifying <span>4y + -70 = 12y + 2
</span>
Add -12y to each side of the equation. -70 + 4y + -12y = 2 + 12y + -12y 

<span>Add 70 to each side of the equation. -70 + 70 + -8y = 2 + 70

Divide each side by -8.
<span>
</span>So y = -9 is your answer.
