11 = 3z + 5

• 2
• 6
• 1
• 4

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.

• Add 11 to both sides

• Subtract 12 from both sides

• Add 12 to both sides

• Divide -11 on both sides.

What was done to solve the equation?

(Line 1) 5x - 8 = 32

(Line 2) 5x = 40

(Line 3) x = 8

• add 8 to both sides, then divide both sides by 5

• add 8 to both sides, then divide both sides by 40

• subtract 8 from both sides, then divide both sides by 5

• subtract 8 from both sides, then multiply both sides by 5

Solve.  x/12 - 8 = -4

• 3
• 12
• 144
• 48

7 + ^a⁄₃ = 5
