Answer:

x = 7/3

Explanation:

To find the of x, isolate it from the other numbers (moving everything to the other side)

What you do to one side, you must do to the other:

3x + 8 = 15

3x + 8 - 8 = 15 - 8 (subtract 8 on both sides to rid of the "+ 8")

3x = 7

3x/3 = 7/3 (divide by 3 on both sides to rid of the 3 attached to "x")

x = 7/3
