Vocabulary

  • Variable = unknown value represented with a letter (x, y, etc.)

  • Isolate = get something by itself (alone)

  • Inverse operations = opposite math operations

  • Multiplication & Division are Inverses

  • Addition & Subtraction are Inverses

  • Property of Equality = solve by doing the same operation on BOTH sides of the equation.

Reciprocals

A fraction flipped is called a reciprocal! When you multiply a fraction by its reciprocal, it equals 1! ("It cancels out")

Ex:

 13(31) = 1\frac{1}{3}\left(\frac{3}{1}\right)\ =\ 1  

 45×54=1\frac{4}{5}\times\frac{5}{4}=1

Add 3 on both sides

2

Multiply by -3 on both sides

3

Divide by -3 on both sides

4

Subtract 3 on both sides
