Distributive Property

The number or variable in front of the parenthesis should be multiplied by EVERYTHING inside the parenthesis.

The answers should then be added or subtracted depending on what sign is in between the numbers.

Letters in an equation take the place of an unknown number

YOU CAN MULTIPLY THE NUMBERS IN FRONT OF LETTERS

YOU CAN'T ADD NUMBERS AND LETTERS TOGETHER

Numbers next to each other like this 2(3) means the numbers are multiplying

The 9 is outside the parenthesis so this is the number that needs to be multiplied by EVERYTHING inside the parenethesis

2 is the number before the () so you will need to multiply it by the 5 and 3

(2x5)+(2x3)

2 should be multiplied by 3x and 1

2(3x) means you multiply the numbers in front of the x

2 should then be multiplied by one

since 6x has an x in it and 2 does not they can't be added.
