Two- Step Equations

Solve 4x + 7 = 23

• x = 16

• x = 4

• x = 9

• x = 12

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

Solve 20 = 2 - a

• a= 18

• a= -18

• a= -10

• a= 12

Solve 7 + ^a⁄₃ = 5

• a= -2

• a= -6

• a= 3

• a= 15

Solve 3c + 5 = 23

• c = 3

• c = 6

• c = 7

• c = 18

Solve -4x+1=21

• x=120

• x=5

• x=30

• x=-5

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
