X=3 because when you add the 7 to both sides you cross out 7 and you then add 2+7 which equals 9. Dividing the 3 on both sides you cancel the 3 out and are left with 9 divided by 3 and that equals 3

x=3 is the answer because you add 7 on both sides to get 3x=9 then you divide 3 on both sides to get x=3
