Answer:

x = 7/3

Step-by-step 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

Answer:

x=2.3

Step-by-step explanation:

15-8=7

Divide 3 on each side (3x=7)7 divided by 3 is 2.3

so X=2.3
