Solving One and Two Step Equations

By:Gemma Giralo

On opposite day SpongeBob did the opposite so if the sign is add you subtract, if the sign is minus you add or

when you divide you multiply and when you multiply you divide. Divide your problem between the equal sign and the number before it. Check your solution!!

REMEMBER: What ever you do to one side you must do to the other.

Example: 6+p=29 d-23=-5

6 6 +23 +23

p= 23 d=18

Step1: Divide your Problem into two between the equal sign and the number before the equal signCircle your variable to show what you are using, like a Krabby Pattie is the most important part of the sandwichGet rid of the number next to the variable by adding or subtracting , when Squidward tries to send SpongeBob awayMultiply or Divide

Check!!!! EXAMPLE: 7q+32=60 32 32 7q=28 7 7 q=4
