Answer:
m=7
Step-by-step explanation:
[tex]\frac{m}{10}-\frac{1}{2}=\frac{1}{5}[/tex]
[tex]\mathrm{Add\:}\frac{1}{2}\mathrm{\:to\:both\:sides}[/tex]
[tex]\frac{m}{10}-\frac{1}{2}+\frac{1}{2}=\frac{1}{5}+\frac{1}{2}[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]\frac{m}{10}=\frac{7}{10}[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:}10[/tex]
[tex]\frac{10m}{10}=\frac{7\cdot \:10}{10}[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]m=7[/tex]
