Question

Using the double number line shown, for the equation 5x+4=14, what is the value of x?

Answer 1

Correct option is:

B. 2

Explanation:

From the double number line shown we can set:

$(1) \ 0x=0 \\ \\ (2) \ x=? \\ \\ (3) \ 5x=10 \\ \\ (4) \ 5x+4=14$

So we can solve this problem by using either equation (3) or (4). So, choosing equation (3):

$5x=10 \\ \\ \\ Divide \ both \ sides \ by \ 5: \\ \\ x=\frac{10}{5} \\ \\ \boxed{x=2}$
