Identify which property was used to find the equivalent expressions. ab = ba
5(3x - 2) = 5(3x) -5(2)
:: Commutative Property of Addition
:: Commutative Property of Multiplication
.. Distributive Property
:: Inverse Property of Addition

Step-by-step explanation:

ab = ba → Commutative Property of Multiplication

5(3x - 2) = 5(3x) - 5(2) → Distributive property

Commutative Property of Addition → a + b = b + a

Inverse Property of Addition → a + (-a) = 0

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
