Question

3n+6 = 15 solve for n please

Answer 1

Step 1: Write out the equation

$3n+6=15$

Step 2: Subtract 6 from both sides of the equation t

$\begin{gathered} 3n+6-6=15-6 \\ 3n=9 \end{gathered}$

Step 3: Divide both sides of the equation by 3

$\begin{gathered} \frac{3n}{3}=\frac{9}{3} \\ n=3 \end{gathered}$

Hence, n = 3
