Verified answer

A
24m = 12
m = 12/24
m = 1/2

B
3z + 11 = -28
3z = -28 - 11
3z = -39
z = -39/3
z = -13

C
25 - 4y = 6y + 15
-4y - 6y = 15 - 25
-10y = -10
y = -10/-10
y = 1

D
⅓ (x - 2) = ⅔ x - 13/3
(x - 2)/3 = (2x - 13)/3
3 (x - 2) = 3 (2x - 13)
3x - 6 = 6x - 39
3x - 6x = -39 + 6
-3x = -33
x = -33/-3
x = 11
