Answer :
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:
[tex](15x)+10=5\times8[/tex]We now solve for x, as follows:
[tex]\begin{gathered} 15x+10=40 \\ 15x=40-10 \\ \frac{15x}{15}=\frac{30}{15} \\ x=2 \end{gathered}[/tex]Hence, the number we are looking for is equal to 2.
