1.2x + 3 = 9
1.2x=9 - 3
1.2x = 6
6/1.2 = 5
Unless 1. is just the number of the problem and not part of it then its
2x + 3 = 9
2x = 9 - 3
2x = 6
6/2 = 3
x = 3
2(3) + 3 = 9
x = 5
1.2(5) + 3 = 9

subtract 3 from both sides ( the 3 and the 9)
9-3=6 so
2x=6 now divide both sides by two because u need to get the x on its own.
6 divided by 2 is 3 so
x=3
