Question

15a-12=6a+24

5y-9=3(y-2)​

Answer 1

1. 15a-12=6a+24

  15a - 6a = 24 + 12

      9a = 36

        a = 4

2. 5y-9=3(y-2)

    5y - 9 = 3y - 6

     5y - 3y = -6 + 9

         2y  = 3

          y = 3/2 = 1,5

3. $\frac{4}{x - 3} = \frac{5}{x - 2}$ (multiplicar en aspa)

4.(x - 2) = 5.(x - 3)

4x - 8 = 5x - 15

15 - 8 = 5x - 4x

  7 = x
