​The Set Up

​The red mirror line reflects the inverse operations!

Write this Down

• ​Circle the coefficient and the variable

• ​Find the inverse operation for the constant

• ​Do this operation to both sides

• ​Find the inverse operation for the coefficient

• ​Do this operation on both sides

Multiple Choice

What is the coefficient and the variable?

3x + 2= 14

• 2

• 14

• 3x

• 12

Multiple Choice

What is the next step to solve this equation?

3x + 2= 14

• Add 2 to both sides

• Subtract 2 on both sides

• Multiply 3

• Find x

Multiple Choice

What’s the next step?

3x =12

• Add 2 to both sides

• Divide 3 on both sides

• Multiply 3 on both sides

• Find x
