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.

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9
• x = 3

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

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.

The goal of solving two-step equations is to:

• francine
• Find the coefficient 
• Find the value of the variable

Solve for x:
-30 - 5x = 120

• x = 18
• x = -18
• x = 30
• x = -30

3x-10+8x=100

• -11
• 100/21
• 10
• -22
