Associative property: When the numbers inside of the parenthesis change with the outside in order to change the expression.
Distributive: When the number on the outside of the parenthesis are distributed with the numbers on the inside of the parenthesis.
Commutative: Numbers that are switched around randomly to change the expression.

Answer:
X = 1
Step-by-step explanation:
2x^2 + x - 1 = 2
2x^2 + x - 3 = 0
2x^2 + 3x -2x - 3 = 0
x(2x+3) -1 ( 2x+3) = 0
(x-1) (2x+3) = 0
x-1=0
x=1
2x+3=0
2x=-3
x=-3/2.

-3a=9
a=-3
3a-3=1
