x-3=12..is that what you meant?

Add 3 to each side to get x alone on one side, and you get x=15.
x/3 = 12

Multiply both sides of the equation by 3.

x = 36
Not so, Marie.

Substitute your answer, 15, for x.

15/3 does not equal 12.
Ms. Sue, I thought the problem was x minus 3 equals 12, so I apologize.
