Question

A number is multiplied by 12 and that product is added to the 6 . The sum is equal to the product of 6 and 15 . Find the the number

Answer 1

So here we have the equation:

(Let "x" be the number).

$12\cdot x+6=6\cdot15$

This is:

$\begin{gathered} 12x+6=90 \\ 12x=90-6 \\ 12x=84 \\ x=\frac{84}{12}=7 \\ x=7 \end{gathered}$
