Question

What is y when 3x -2y=12

Answer 1

x=12         y=12

3x-2y=12

Divide both sides by 3

x-2/3y=4

x=4+2/3y

3(4+2/3y)-2y=12

12+2y-2y=12

12=12

y=12      x=12

3*12-2*12=12

36-24=12

x=4+2/312=4+8=12

Answer 2

Y = 3/2x -6

1) canceled out the 3x by using the subtraction property of equality.

2) dividing all terms by -2 on both sides.

3) resulting in getting Y = 3/2x - 6
