Question

Which of the following is equal to (3x/5-7)+7?

Answer 1

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

Answer 2

For this case we have the following expression:

$(\frac{3x}{5}-7)+7$

We can solve the problem by associative property for addition.

Applying the associative property we have:

$\frac{3x}{5}+(-7+7)$

Rewriting we have:

$\frac{3x}{5}+0$

$\frac{3x}{5}$

Answer:

The equivalent expression is given by:

$\frac{3x}{5}$

option B
