Question

Is the following always, sometimes, or never true?

Answer 1

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

Answer 2

Out of the choices given, the following equation " 14+3x-7x+4-4x" is always true. The correct answer will be A.
