Pre Algebra Solving One Step Equations

I need to first identify what before I can solve a one step equation?

• The Variable

• The Equals Sign

• I don't pay attention in class and have no clue

A variable is an unknown quantity that is usually represented by "x"

• True

• False

• I don't know because I don't listen

Identifying the mathematical operation that is next to the variable is something I need to do to solve a one-step equation?

• True

• False

Once you identify the mathematical operation, DO THE INVERSE (opposite) operation to both sides of the equation to solve for the variable.

• False

• True

Addition and subtraction are inverse operations

• True

• False

• Almost always false

• Only true every other odd numbered Saturday

Multiplication and division are inverse operations

• True

• False

• Not sure, because I'm usually wandering the hallway
