\frac{4}{3}\times 2-\frac{2}{3}x\times 2+3x=6
Use the distributive property to multiply \frac{4}{3}-\frac{2}{3}x by 2.
\frac{4\times 2}{3}-\frac{2}{3}x\times 2+3x=6
Express \frac{4}{3}\times 2 as a single fraction.
\frac{8}{3}-\frac{2}{3}x\times 2+3x=6
Multiply 4 and 2 to get 8.
\frac{8}{3}+\frac{-2\times 2}{3}x+3x=6
Express -\frac{2}{3}\times 2 as a single fraction.
\frac{8}{3}+\frac{-4}{3}x+3x=6
Multiply -2 and 2 to get -4.
\frac{8}{3}-\frac{4}{3}x+3x=6
Fraction \frac{-4}{3} can be rewritten as -\frac{4}{3} by extracting the negative sign.
\frac{8}{3}+\frac{5}{3}x=6
Combine -\frac{4}{3}x and 3x to get \frac{5}{3}x.
\frac{5}{3}x=6-\frac{8}{3}
Subtract \frac{8}{3} from both sides.
\frac{5}{3}x=\frac{18}{3}-\frac{8}{3}
Convert 6 to fraction \frac{18}{3}.
\frac{5}{3}x=\frac{18-8}{3}
Since \frac{18}{3} and \frac{8}{3} have the same denominator, subtract them by subtracting their numerators.
\frac{5}{3}x=\frac{10}{3}
Subtract 8 from 18 to get 10.
x=\frac{10}{3}\times \frac{3}{5}
Multiply both sides by \frac{3}{5}, the reciprocal of \frac{5}{3}.
x=\frac{10\times 3}{3\times 5}
Multiply \frac{10}{3} times \frac{3}{5} by multiplying numerator times numerator and denominator times denominator.
x=\frac{10}{5}
Cancel out 3 in both numerator and denominator.
x=2
Divide 10 by 5 to get 2.
