Answer:

y= -3, x= -3

Step-by-step explanation:

Add the 2 equations to get rid of x:

-5y = 15

Divide both sides by 5:

y = -3

Substitute value of y into an equation to get x (I chose the first one

10x-8y = -6)

10x-8(-3) = -6

10x+24 = -6

Subtract both sides by 24:

10x = -30

Divide both sides by 10:

x = -3
