you put the 7 to the other side, making it minus 7
so
5x = 27 - 7
5x = 20
then divide both sides by 5 (to cancel out the 5 of the 5x)
5x/5 = 20/5
x= 4

5x+7 = 27
5x+7-7 = 27-7
5x = 20
5x/5 = 20/5
x = 4

27= 5x +7 Subtract 7 from both sides to isolate x to 1 side
- 7= -7
____________
20 = 5x divide 5 on both sides
4 = x
