x - 8 = -5 

• 13
• -13
• 3
• -3

19  + a  =  -50

• a = -950
• a =  -69
• a = -31
• a = -50/19

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

15 = 2a + 7

• 2
• 4
• 12
• 14

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.

What is a two-step equation?

• An equation where two steps (or operations) are needed to solve it.
• An equation where only one step is needed to solve it.
• A problem with only one operation present.
• A problem where you find the square-root of a number.

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 
• Subtract 62 from each side.
• Multiply each side by 62.
• Add 123 to each side.

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.
