x-2=\frac{3}{8}\times 3+\frac{3}{8}\left(-1\right)x
Use the distributive property to multiply \frac{3}{8} by 3-x.
x-2=\frac{3\times 3}{8}+\frac{3}{8}\left(-1\right)x
Express \frac{3}{8}\times 3 as a single fraction.
x-2=\frac{9}{8}+\frac{3}{8}\left(-1\right)x
Multiply 3 and 3 to get 9.
x-2=\frac{9}{8}-\frac{3}{8}x
Multiply \frac{3}{8} and -1 to get -\frac{3}{8}.
x-2+\frac{3}{8}x=\frac{9}{8}
Add \frac{3}{8}x to both sides.
\frac{11}{8}x-2=\frac{9}{8}
Combine x and \frac{3}{8}x to get \frac{11}{8}x.
\frac{11}{8}x=\frac{9}{8}+2
Add 2 to both sides.
\frac{11}{8}x=\frac{9}{8}+\frac{16}{8}
Convert 2 to fraction \frac{16}{8}.
\frac{11}{8}x=\frac{9+16}{8}
Since \frac{9}{8} and \frac{16}{8} have the same denominator, add them by adding their numerators.
\frac{11}{8}x=\frac{25}{8}
Add 9 and 16 to get 25.
x=\frac{25}{8}\times \frac{8}{11}
Multiply both sides by \frac{8}{11}, the reciprocal of \frac{11}{8}.
x=\frac{25\times 8}{8\times 11}
Multiply \frac{25}{8} times \frac{8}{11} by multiplying numerator times numerator and denominator times denominator.
x=\frac{25}{11}
Cancel out 8 in both numerator and denominator.
