Question

Translate into an equation and solve. Thirteen equals nineteen less than the product of eight and a number. Find the number.

Answer 1

Let x represent the number then:

$13=8x-19.$

Now, to solve for x, first, you add 19 to both sides of the equation:

$\begin{gathered} 13+19=8x, \\ 32=8x. \end{gathered}$

Finally, dividing by 8, you get:

$\begin{gathered} 8x=32, \\ x=\frac{32}{8}, \\ x=4. \end{gathered}$

Answer:

$4.$
