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.

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

Match the following equation with the first step you would perform to solve.

• add 3 to both sides

• 3x - 5 = 9

• subtract 3 from both sides

• 5x + 3 = 1

• subtract 5 from both sides

• 5x - 3 = 21

• add 5 to both sides

• 3x + 5 = 6

• No Solution

• Infinitely Many Solutions

• 1=x

• -6=3x-9

• 3=3x

• 2x-6=5x-9
