Equations and Slope

Solve for y.
-2y=20

• y=-10
• y=2
• y=-20
• y=15

-5z+5=-30

• z=7
• z=6
• z=5
• z=35

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

-4x+1=21

• x=120
• x=5
• x=30
• x=-5

20 = 2 - a

• a= 18
• a= -18
• a= -10
• a= 12

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

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.

6p - 5 =13

• 12
• 15
