Model and Solve One-Variable, Two-Step Equations

What is equation for this model?

• 2x + 3 = 5

• 2x - 3 = 5

• 2 - 3 = 5

• 2 + -3 = 5

What is the equation for this model ?

• 3x + 4 = 13

• 3x - 4 = -1

• 6x = 14

• -3x + 4 = 13

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.
