• Subtract 5 from 12

• Subtract 5 from both sides

• Add 5 to both sides

• Add 5 to 12

Answer explanation

Remember, you need to keep the equation  balanced! Whatever you do to one side you must do to the other!! (keep Lola safe on the seesaw)

What would be the correct first step to solve the equation

 $9\ =\ x\ +\ 8$  

• Subtract 8 from 9

• Subtract 8 from both sides

• Subtract 9 from both sides

• Add 8 to both sides

Answer explanation

The goal is to find out what x is equal to. 

To do this, we need to isolate the variable (we need to get the variable by itself).  

8 is being added to x which is what is stopping x from being alone. 

The inverse of addition is subtraction so we must subtract 8 from both sides.
