    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.
