3. Learn to solve multi-step equations.

4. Example A
Solve b -7b = 18.
b -7b = 18
12 + 3b = 18
Combine like terms.
– – 12
Subtract 12 from both sides.
3b = 6
3b = 6
Divide both sides by 3.
b = 2

5. Example B
Solve 2 – 7n +14n = 37.
2 -7n + 14n = 37
2 + 7n = 37
Combine like terms.
– – 2
Subtract 2 from both sides.
7n = 35
7n = 35
Divide both sides by 7.
n = 5

6. Example B
Solve -27 = -3p + 15 – 3p
-27 = -3p + 15 – 3p
-27= -6p + 15
Combine like terms.
– – 15
Subtract 15 from both sides.
-42 = -6p
-42 = -6p
Divide both sides by -6.
7 = p

7. You try 1
14 – 8b + 12b = 62
14 – 8b + 12b = 62
14 + 4b = 62
Combine like terms.
– – 14
Subtract 14 from both sides.
4b = 48
4b = 48
Divide both sides by 4.
b = 12

8. m + 29 + 8m = 110 You try 2 9m + 29 = 110 Combine like terms.
– – 29
Subtract 29 from both sides.
9m = 81
9m = 81
Divide both sides by 9.
m = 9
