Solving One Step Equations

y/3=12. What is being done to Y and what do you do to isolate the variable?

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

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

• 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.
