3/10 n-3 1/5=-1 1/5
convert mixed numbers to a improper fractions:3 1/5=16/5
[tex] \frac{3}{10}n- \frac{16}{5}=-1* \frac{1}{5}[/tex]
convert mixed numbers to a improper fractions:1 1/5=6/5
[tex] \frac{3}{10}n- \frac{16}{5}=- \frac{6}{5} [/tex]
add 16/5 to both sides
[tex] \frac{3}{10}- \frac{16}{5}+ \frac{16}{5}=- \frac{6}{5}+ \frac{16}{5} [/tex]
simplify
3/10 n=2
multiply both sides by 10
[tex]10* \frac{3}{10}n=2*10 [/tex]
simplify
3n=20
divide both sides by 3
[tex] \frac{3n}{5}= \frac{20}{3} [/tex]
simplify
[tex]n= \frac{20}{3} [/tex]
Hope this helps
