2. Do Now
Solve.
1. 6n + 8 – 4n = 20
2. –4w + 16 – 4w = –32
3. 25t – 17 – 13t = 67
4. 12 = 2(x + 7) + 4
n = 6
w = 6
t = 7
x = –3

3. To solve equations with variables on both sides:
first collect like terms on the same side
then use the inverse operations to solve.
Solve.
1. 60 – 4y = 8y
2. 40 – 2y = 6y
+ 4y
+ 4y
+ 2y
+ 2y 60
= 12y 40
= 8y 12 12 8 8
5 = y
5 = y

4. To solve equations with variables on both sides:
first collect like terms on the same side
then use the inverse operations to solve.
3. –5b + 72 = –2b
4. –8b + 24 = –5b
+ 5b
+ 5b
+ 8b
+ 8b 72
= 3b 24
= 3b 3 3 3 3
24 = b
8 = b

5. To solve equations with variables on both sides:
first collect like terms on the same side
then use the inverse operations to solve.
5. 7c = 2c + 55
– 3m = 4m + 14
– 2c
– 2c

c = 11
35 = 7m 7 7
5 = m

6. To solve equations with variables on both sides:
first collect like terms on the same side
then use the inverse operations to solve.
7. 8f = 3f + 65
– 3q = 6q + 9

– 3f
– 3f 5f
= 65 54
= 9q + 9 5 5

f= 13 9q
45 = 9 9
5 = q

7. Practice- Solve.
9. 14n = 11n + 81
10. –14k + 12 = –18k
