subtract 15/2 from both sides
then you have
5/2 x = 15/2
multiply both sides by 2
then divide both sides by 5
to find x

(5/2)x+15/2=15
(5/2)x = 15  15/2
(5/2)x = 15/2
This much campbell_st already showed you
Multiply both sides by 2
5x = 15
Divide both sides by 5
x = 3

If so, first, multiply both sides by 2.

That will get rid of the denominator of the left side.

Then subtract 4 from both sides.
