Two Step Equations

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.

20 = 2 - a

• a= 18
• a= -18
• a= -10
• a= 12

7 + ^a⁄₃ = 5

• a= -2
• a= -6
• a= 3
• a= 15

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

-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

11 = 3z + 5

• 2
• 6
• 1
• 4

2s - 4 = 6

• 5
• 3
• -5
• 2

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18
