A. 32 = 3s + 8
minus 8 from both sides
24 = 3s
divide by 3
s = 8
B: Q/10 = 6
multiply by 10 on both sides
Q = 6 × 10
Q = 60
C: 2b -1 = 7
add 1 to both sides
2b = 8
divide by 2
b = 4
D: d/8 = 2
multiply by 8 on both sides
d = 2 ×8
d = 16
E: 10u + 5 = 45
minus 5 from both sides
10u = 40
divide by 10
u = 4
F: j/11 = 7
multiply by 11 on both sides
j = 7 × 11
j = 77
