Answer 1

Let x represent the number, then 3 times x is in algebraic notation:

$3x,$

the sum of 3x and 15 in algebraic notation is:

$3x+15.$

Now, the above expression is equivalent to: (x=n)

$\begin{gathered} 15+3\times n, \\ 15+3n, \\ (n\times3)+15. \end{gathered}$

Answer:

$\begin{gathered} 15+3n, \\ 15+3\times n, \\ (n\times3)+15. \end{gathered}$
