Grade 7 = Equations and Inequalities Review

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

18+m=38

• m=0

• m=10

• m=20

• m=8

144=12z

• z=20
• z=11
• z=12

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

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: x/2 = -10

• 20
