Answer:
x=-2
Explanation:
you move the numbers on one side and the variables on the other. Here I decided to move the variable to the right side and the numbers to the left. to do that I have to add 2x on each side to get rid of the -2x on the left and subtract 12 from each side to get rid of the positive 12 on the right. Now we got -4=2x, but here we are looking for x so i divide by 2 on each side and end up with -2=x
