\frac{1}{3}+2x+\frac{6}{3}=2
Convert 2 to fraction \frac{6}{3}.
\frac{1+6}{3}+2x=2
Since \frac{1}{3} and \frac{6}{3} have the same denominator, add them by adding their numerators.
\frac{7}{3}+2x=2
Add 1 and 6 to get 7.
2x=2-\frac{7}{3}
Subtract \frac{7}{3} from both sides.
2x=\frac{6}{3}-\frac{7}{3}
Convert 2 to fraction \frac{6}{3}.
2x=\frac{6-7}{3}
Since \frac{6}{3} and \frac{7}{3} have the same denominator, subtract them by subtracting their numerators.
2x=-\frac{1}{3}
Subtract 7 from 6 to get -1.
x=\frac{-\frac{1}{3}}{2}
Divide both sides by 2.
x=\frac{-1}{3\times 2}
Express \frac{-\frac{1}{3}}{2} as a single fraction.
x=\frac{-1}{6}
Multiply 3 and 2 to get 6.
x=-\frac{1}{6}
Fraction \frac{-1}{6} can be rewritten as -\frac{1}{6} by extracting the negative sign.
