hello
the equation given is
[tex]\frac{n}{10}+4=8[/tex]to solve for n, we need to follow some steps which are
step 1
collect like terms
[tex]\begin{gathered} \frac{n}{10}+4=8 \\ \frac{n}{10}=8-4 \\ \frac{n}{10}=4 \\ \end{gathered}[/tex]step 2
cross multiply both sides to solve for n
[tex]\begin{gathered} \frac{n}{10}=4 \\ n\times1=4\times10 \\ n=40 \end{gathered}[/tex]from the calculations above, the value of n = 40
