Question

I need help. again. I am trying to solve each system of the equations. BTW I am in pre algebra. thank u

Answer 1

2y = 27 + 4x 

Is this what you need?

Answer 2

Same idea here as last time.
You have a y-value, substitute it in the problem.
y=x+12
4x+2y=27
4x+2(x+12)=27
4x+2x+24=27
6x+24=27
-24      -24
6x=3
/6
x=.5

plug back in
y=(.5)+12
y=12.5

final answer:
x=.5,y=12.5
