• 10
• 12
• 11
• 13

m+13=21

• m=34
• m=8
• m=273
• m=6

What is the first step to solve for b:

2b = -16

• add 2 to both sides

• subtract 2 to both sides

• multiply 2 to both sides

• divide 2 to both sides

12g - 5 = 19

Which is the correct 1st step?

• Add 12 to both sides

• Add 5 to both sides

• Add 19 to both sides

• Multiply both sides by 12

• Divide both sides by 12

• Multiply both sides by 24

• Divide both sides by 24

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 for x

• x = 2

• x = -2

• x = -10

• x = 4
