Question

A number is multiplied by 15 and that product is added to 10. The sum is equal to the product of 5 and 8. Find the number

Answer 1

We first let x be the number that will be multiplied to 15 and further be added to 10. The sum is equal to the product of 5 and 8. We can write this in the mathematical equation as:

`(15x)+10=5*8`

We now solve for x, as follows:

`\begin{gathered} 15x+10=40 \\ 15x=40-10 \\ (15x)/(15)=(30)/(15) \\ x=2 \end{gathered}`

Hence, the number we are looking for is equal to 2.

Answer: 2
