120=\frac{7}{3}x
Combine 2x and \frac{1}{3}x to get \frac{7}{3}x.
\frac{7}{3}x=120
Swap sides so that all variable terms are on the left hand side.
x=120\times \frac{3}{7}
Multiply both sides by \frac{3}{7}, the reciprocal of \frac{7}{3}.
x=\frac{120\times 3}{7}
Express 120\times \frac{3}{7} as a single fraction.
x=\frac{360}{7}
Multiply 120 and 3 to get 360.
