-2/3x=12 (because we moved the 12 to the other side)

What is 2/3 of 12? (12/2=6*3=18).

Your answer is 18.

Let's try this again, this time keeping track of the negative signs. Assuming the equation you want solved is this:
%28-2%2F3%29%2Ax+-+12+=+0
First, add 12 to both sides:
%28-2%2F3%29%2Ax+-+12+%2B+12+=+0+%2B+12
%28-2%2F3%29%2Ax+=+12
Next, divide both sides by -2%2F3, which is the same as multiplying by its reciprocal, -3%2F2
%28-3%2F2%29%2A%28-2%2F3%29%2Ax+=+%28-3%2F2%29%2A12
x+=+%28-3%2A12%29%2F2
x+=+-36%2F2
x+=+-18
