Simplify by combining like terms:
5a + 2b - 3a + 4

• 8a + 2b + 4

• 2a + 2b + 4

• 8ab

• 4ab + 4

r + 20 = 27

• r = 7

• r = 47

• r = 13

• r = 20

6x = 30

• x = 5

• x = 24

• x = 6

• x = 36

t/8 = 5

• t = 3

• t = 13

• t = 44

• t = 40

3c + 5 = 23

• c = 3

• c = 6

• c = 7

• c = 18

Solve   -5t + 9 = 24

• -3

• 3

• -5

• 12

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5
