How to solve a Distributive Property equation
3(x - 4) = 9
x - 4
x - 4
x - 4
---------
3x - 12 = 12
3 groups of a number and 3 is 12

Example:
5 z + 2
5 z + 2 - 2 = 22 - 2
5 z = 20
---------
5      5
x = 4

Verify:
5 z + 2 = 22
5 (4) + 2 =
20 + 2 = 22
22 = 22

Constant - A number that does not change

Coefficient - The number that is multiplying the variable

Variable - A letter that represents an unknown number. In 5z - 3 the variable is "z"
