6=\frac{3}{10}x
Combine \frac{2}{5}x and -\frac{1}{10}x to get \frac{3}{10}x.
\frac{3}{10}x=6
Swap sides so that all variable terms are on the left hand side.
x=6\times \frac{10}{3}
Multiply both sides by \frac{10}{3}, the reciprocal of \frac{3}{10}.
x=\frac{6\times 10}{3}
Express 6\times \frac{10}{3} as a single fraction.
x=\frac{60}{3}
Multiply 6 and 10 to get 60.
x=20
Divide 60 by 3 to get 20.
