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} (3n)/(3)=(9)/(3) \\ n=3 \end{gathered}`

Hence, n = 3
