ONE STEP EQUATIONS

1. Isolate the variable
(Variable - The unknown number and you use a letter to represent the number.)

2. Cancel using the opposite
-create a zero pair for the constant
(Constant - The integer in an algebraic expression or equation.)
2x = 6 equation, 2x = expression

3. Balance on the other side of the equal sign

4. Verify your answer

Eg:
A number and 16 is 9.










The difference of a number and 15 is -27.









Eight times a number is -104.









A number divided by 18 is -6.
