Answer:

x = 1/3

Step-by-step explanation:

15 = 1/2 + 3/2x + 10

15 - 1/2 -10 = 3/2x

9/2 = 3/2x

9 x 2x = 3 x 2

18x = 6

x = 6/18

x = 1/3

Answer:

x = 3

Step-by-step explanation:

15 = 1/2 + 3/2x + 10                  

14.5 = 3/2x + 10                      Subtract 1/2 to both sides

4.5 = 3/2x                               Subtract 10 to both sides

3 = x                                        Divide 3/2 to both sides
