Solving One Step Equations

When solving for X you need to _____________ the variable.

• Add

• Change

• Isolate

What does inverse operation mean?

• Same operation

• Oposite operation

Which of the following are correct inverse operations?

• Addition is the inverse operation of Subtraction

• Multiplication is the inverse operation of Addition

• Multiplication is the inverse operation of Division

• Subtraction is the inverse operation of Division

What is being done to Y and what do you do to isolate the variable? $\frac{y}{3}=12$  

• Y is being divided by 3, so you need to divide both sides by 3.

• Y is being divided by 3, so you need to multiply both sides by 3.

• Y is being divided by 3, so you need to add 3 to both sides.

• 3 is being added to Y, so you need to subtract 3 from both sides.

To solve the equation:

4p = 16

what needs to be done to both sides to isolate the variable?

• Add 4

• Multiply by 4

• Subtract 4

• Divide by 4

What is the correct step to solve for the variable?

15 = m - 5

• add 15 to both sides

• subtract 15 from both sides

• add 5 to both sides

• subtract 5 from both sides
