3. Determining Solutions of Equations
a + 23 = 82 for a =61
a + 23 = 82
= 82
84 = 82
60 ÷ c = 6 for c = 10
60 ÷ 10 = 6
6 = 6

4. Examples: c + 23 = 48 for c = 35 z + 31 = 73 for z =42
96 = 130 – d for d = 34
85 = a for a = 105
75 ÷ y = 5 for y = 15
78 ÷ n = 13 for n = 5
w + 19 = 49 for w =30
d + 27 = 81 for d = 44
g + 34= -33 for g = 67
101 = 150 – h for h = 49
