-3x + 18 = 7x - 12

we want to get x on only one side so you would add 3x to 7x

18 = 10x - 12

next, we want the 18 and 12 on the same side so you add 12 to 18

30 = 10x

finally we want the x by itself so you will divide 10x and 30 (since you need to do it for both sides) by 10

final answer:

10 = x

x = 10
