\(\frac15n+\frac32=\frac3{10}n\)             Subtract  \(\frac15n\)  from both sides of the equation.

 

\(\frac32=\frac3{10}n-\frac15n \\~\\ \frac32=\frac3{10}n-\frac2{10}n\)

 

\(\frac32=\frac1{10}n\)                        Multiply both sides of the equation by  10  .

 

\(10\,*\,\frac{3}2=n \\~\\ \frac{30}{2}=n \\~\\ 15=n\)
