Two Step Equations Overview

What is the overall goal when solving equations?

• To find a missing value

• To isolate the variable

• To solve for the given variable

• All of the above

What do we use in order to solve equations?

• Inverse

• Operations

• Order of operations

• Inverse Operations

What ever we do to one side, we do to the other.

• True

• False

What is the first step to solving x + 3 = 10?

• Multiply both sides by 3

• Divide both sides by 3

• Add 3 to both sides

• Subtract 3 from both sides

What is the first step to solving x - 5 = -3?

• Multiply both sides by (-5)

• Divide both sides by (-5)

• Add 5 to both sides

• Subtract (-5) from both sides

How would we solve (2/3)x = 16?

• Invert the fraction, then multiply by (3/2) on both sides

• Divide by (3/2) on both sides

• Subtract (2/3) on both sides

• Add (2/3) on both sides

What is the second step to solving 3x + 4 = 10?

• Subtract 4 from both sides

• Divide both sides by 3

• Multiply both sides by 4

• Add 10 to both sides

What would the second step to solving (x/7) - 8 = 6?

• Multiply both sides by 7

• Divide both sides by 7

• Add 8 to both sides

• Subtract 8 from both sides

What is the first step to solving -3x + 5 =15

• Subtract 5 from both sides

• Add 5 to both sides

• Divide both sides by -3

• Multiply -3 on both sides

Solve x + 2 = 10
