2 step equations #2

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

Solve each equation for the following variable. 
1.     x - 4 = 12

• x = 8
• x = 16
• x = -8
• x = 3

2x + 16 = 130

• x=114
• x=57
• x=-114
• x=-57

2x + 6 = 18

• x = 12

• x = -6

• x = 6

• x = -12

4x - 5 = 11

• x = -4

• x = 6

• x = -6

• x = 4

3x - 9 = 9

• x = 0

• x = 6

• x = 18

• x = 3

Solve 2x - 3 = 1 

• 3
• 2
• 1
• -2

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

15 = 2a + 7

• 2
• 4
• 12
• 14
