One and Two Step Equations

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

144=12z

• z=20
• z=11
• z=12

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

2.     2x + 6 = 14

• x = 4
• x = 10
• x = -4
• x = 3

15 = 2a + 7

• 2
• 4
• 12
• 14

What is the solution of 6d = 24

• d = 4

• d = 5

• d = 18

• d = 144

u/4=12

• u = 3

• u = 8

• u = 16

• u = 48

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 inverse operation needed to solve for p?
765 = p - 254

• subtraction
• addition

• division

What is a one-step equation?

• A problem where multiple operations are present.
• A problem where the variable is missing.
• An equation where only one step (operation) is needed to solve it.
• An equation where two steps (two operations) are needed to solve it.
