Variable

A letter (${\displaystyle a}$-${\displaystyle z}$) that takes the place of a number.

Equation

An example would be like ${\displaystyle 8y-3=1+10y}$ (The answer is ${\displaystyle y=-2}$ )

Lesson

NOTE: WHAT YOU DO TO ONE SIDE YOU MUST DO TO THE OTHER SIDE! NO EXCEPTIONS!

1) do the distributive property.

2) Combine like terms on both sides.

3) add/subtract numbers next to a variable on both sides.

4) divide by the number next to the variable on both sides.

5) The answer should look like: ${\displaystyle x=20}$ or ${\displaystyle 20=x}$.

(Note: the variables and numbers may vary in your answer.)
