a. 5x/3
b. 3x/5
c. 3x-35/5
d. (3x-7)+35

Answer 1

For this case we have the following expression:

`((3x)/(5)-7)+7`

We can solve the problem by associative property for addition.

Applying the associative property we have:

`(3x)/(5)+(-7+7)`

Rewriting we have:

`(3x)/(5)+0`

`(3x)/(5)`

Answer:

The equivalent expression is given by:

`(3x)/(5)`

option B

Answer 2

(3x/5-7)+7= 3x/5-7+7= 3x/5 +(-7+7)= 3x/5+0=3x/5
the answer is b. 3x/5
