For this case we have the following expression:

14 + 3x - 7 = 7x + 7 - 4x

To answer the question, what we must do is rewrite both sides of the equation.

For this, we apply the associative property.

We have then:

3x + (14-7) = (7x-4x) + 7

Rewriting we have:

3x + 7 = 3x + 7

Since both sides of the equation are equal, then the expression is always true.

Answer:

A) Always
