Homework #10

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.

-4x+1=21

• x=120
• x=5
• x=30
• x=-5

Solve the equation for x:
2x + 3x + 4 = 44

• x = 8
• x = 9
• x = 10
• x = 11

3(3x - 6) = 18

• x = 4
• x = -4
• x=8
• x= -12
