\frac{7}{3}x=21
Combine 2x and \frac{1}{3}x to get \frac{7}{3}x.
x=21\times \frac{3}{7}
Multiply both sides by \frac{3}{7}, the reciprocal of \frac{7}{3}.
x=\frac{21\times 3}{7}
Express 21\times \frac{3}{7} as a single fraction.
x=\frac{63}{7}
Multiply 21 and 3 to get 63.
x=9
Divide 63 by 7 to get 9.
