Answer 2

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

d]
1/3(x - 2) = 2/3 x - 13/3
x - 2 = (2/3 x - 13/3)/(1/3)
x - 2 = (2/3 x - 13/3) × 3
x - 2 = 2x - 13
x - 2x = -13 + 2
-x = -11
x = -11/-1
x = 11

e]
2(1/2 x + 3/2) - 7/2 = 3/2(x + 1) - (1/2 x + 2)
x + 3 - 7/2 = 3/2 x + 3/2 - 1/2 x - 2
2x/2 + 6/2 - 7/2 = 3/2 x - 1/2 x + 3/2 - 4/2
2x/2 - 1/2 = 2/2 x - 1/2
x - 1/2 = x - 1/2
x - x = -1/2 + 1/2
0 = 0
