Question

15-4x=3 what is the value of x

Answer 1

You have to solve the given expression for x. To do so, you have to isolate the x-term on one side of the equal sign.

$15-4x=3$

- First, subtract 15 to both sides of the equation to pass the term to the right side of the equal sign:

$\begin{gathered} 15-15-4x=3-15 \\ -4x=-12 \end{gathered}$

-Second, divide both sides by -4 to cancel the multiplication on the x-term and determine the value of x:

$\begin{gathered} \frac{-4x}{-4}=\frac{-12}{-4} \\ x=3 \end{gathered}$
