Solving Equations Practice

6 - 3a = 21

• a= 9
• a= -9
• a= -5
• a= 5

• a= -2

• a= -6

• a= 3

• a= 15

2k + 12 = -4

• -8
• 8
• -10
• 4

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5

Solve for p in the following equation:

4p = 16

• p = 12

• p = 64

• p = 3

• p = 4

• x = 35
  

• x = 0
  

• x = 21
  

• x = 14
