\frac{4}{3}x-2=-x+3
Combine 2x and -\frac{2}{3}x to get \frac{4}{3}x.
\frac{4}{3}x-2+x=3
Add x to both sides.
\frac{7}{3}x-2=3
Combine \frac{4}{3}x and x to get \frac{7}{3}x.
\frac{7}{3}x=3+2
Add 2 to both sides.
\frac{7}{3}x=5
Add 3 and 2 to get 5.
x=5\times \frac{3}{7}
Multiply both sides by \frac{3}{7}, the reciprocal of \frac{7}{3}.
x=\frac{5\times 3}{7}
Express 5\times \frac{3}{7} as a single fraction.
x=\frac{15}{7}
Multiply 5 and 3 to get 15.
