Question

What properties were used to prove that the expressions 7x + 4 - x - 2 and 6x + 2 are equivalent

Answer 1

they are equivalent

Explanation:

for 7x+4-x-2, combine the like terms first. Do 7x-x (x by itself is the same thing as 1x) to get 6x. Then, do 4-2 to get 2. You get 6x+2, which is equivalent to 6x+2.

Answer 2

I THINK the answer is distributive, associative, and commutative

Explanation:

The equation, 7x+4-x-2, is distributive proporty.

The equation, 7x-x+4-2 is commutative

The equation, ( 7-1 ) x+4-2 is distributive

Sorry if I’m wrong

Best of luck
