Question

Please help! A is not -3 as I’ve seen some answer with that.

Answer 1

Answer:

a) x = 5

b) x = 4

Step-by-step explanation:

a) $\frac{3x+4}{2}$ = 9.5

  3x+4 = 9.5(2)

      3x = 19-4

        x = 15/3

         x = 5

b) $\frac{7+2x}{3}$ = 5

  7+2x = 5(3)

      2x = 15-7

        x = 8/2

         x=4
