Question

X - 3y = 10
x+5y=-22

Answer 1

x=-2

y=-4

Explanation:

x - 3y = 10 (1)

x + 5y = -22 (2)

Multiply equation (1) by -1:

-x+3y=-10

Add this new equation to equation 2:

8y=-32

Divide both sides by 8:

y=-4

Substitute this value for y into equation (1):

x-3(-4)=10

Simplify:

x+12=10

Subtract 12 from both sides:

x=-2
