Question

Please need help with number 9 and 10!! With solution needed please!!

Answer 1

9. m = 7

10. z = (-12)

Explanation:

9.

`8(m + 3) = 5(m + 9) \\ 8m + 24 = 5m + 45 \\ 8m - 5m = 45 - 24 \\ 3m = 21 \\ (3m)/(3) = (21)/(3) \\ m = 7 \\`

10.

`(z - 6)/(2z) = (3)/(4) \\ 4(z - 6) = 3(2z) \\ 4z - 24 = 6z \\ - 24 = 6z - 4z \\ - 24 = 2z \\ ( - 24)/(2) = (2z)/(2) \\ ( - 12) = z \\`
