Two Step Equations

What is the first step in this equation?

3x + 5 = 20

• Add 5 and 20

• Subtract 5 from both sides of the equation

• Add 3 and 5

• Multiply 3 by 5

• Multiply both sides by 12

• Divide both sides by 12

• Multiply both sides by 24

• Divide both sides by 24

2t -7 = 3

Find the value of t

• -2

• 2

• 5

• 20

Solve  3x - 7 = 32

• 13
• -13
• 12
• -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

-4x+1=21

• x=120
• x=5
• x=30
• x=-5

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

• Add 15 to both sides

• Subtract 15 from both sides

• Multiply by 4 on both sides

• Divide by 4 on both sides

• Add 6 on both sides

• Subtract 6 on both sides

• Divide by -9 on both sides

• Divide by 9 on both sides

Solve -5t + 9 = 24

• -3

• 3

• 12
