Y=1/2x + 5

Y=-3/2x-7

Find x and y

I'm going to use the substitution method.

If y = - 3/2 - 7, then:

1/2x + 5 = - 3/2x - 7

Combine like terms:

4/2x = - 12. Mutiply both sides by 2/4 to get x = - 12 (2/4)

Simplify to get:

x = - 6.

Plug - 6 back in for x in either equation.

Y = 1/2 ( - 6) + 5 which becomes Y = - 3 + 5.

X = - 6, Y = 2
