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=(32)/(8), \\ x=4. \end{gathered}`

Answer:

`4.`
