Question

How many solutions are there to the equation below?

5x + 48 + 7x = 12 (x + 4)

A. 0

B. Infinitely many

C. 1

ANSWER: B (Infinitely many)

Answer 1

Answer:

$5x + 48 + 7x = 12(x + 4) \\ 5x + 48 + 7x = 12x + 48 \\ (5x + 7x) + 48 = 12x + 48 \\ 12x + 48 = 12x + 48 \\ 12x - 12x = 48 - 48 \\ 0 = 0$

There is no solution

Answer 2

It’s 0. Hope it’s works.
