24m = 12
m = 12/24
m = 1/2 atau 0,5

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

25 - 4y = 6y + 15
25 - 4y - 6y - 15 = 0
10 - 10y = 0
-10y = -10
y = -10/-10
y = 1

1/3(x-2) = 2/3x - 13/3
1/3x - 2/3 = 2/3x - 13/3
1/3x - 2/3 - 2/3x + 13/3 = 0
-1/3x + 11/3 = 0
-1/3x = -11/3
x = -11/3 / -1/3
x = 11
