\frac{3\times 9}{7}+x=6
Express 3\times \frac{9}{7} as a single fraction.
\frac{27}{7}+x=6
Multiply 3 and 9 to get 27.
x=6-\frac{27}{7}
Subtract \frac{27}{7} from both sides.
x=\frac{42}{7}-\frac{27}{7}
Convert 6 to fraction \frac{42}{7}.
x=\frac{42-27}{7}
Since \frac{42}{7} and \frac{27}{7} have the same denominator, subtract them by subtracting their numerators.
x=\frac{15}{7}
Subtract 27 from 42 to get 15.
