3x-27+x=\frac{1}{3}\left(x-3\right)
Use the distributive property to multiply 3 by x-9.
4x-27=\frac{1}{3}\left(x-3\right)
Combine 3x and x to get 4x.
4x-27=\frac{1}{3}x+\frac{1}{3}\left(-3\right)
Use the distributive property to multiply \frac{1}{3} by x-3.
4x-27=\frac{1}{3}x+\frac{-3}{3}
Multiply \frac{1}{3} and -3 to get \frac{-3}{3}.
4x-27=\frac{1}{3}x-1
Divide -3 by 3 to get -1.
4x-27-\frac{1}{3}x=-1
Subtract \frac{1}{3}x from both sides.
\frac{11}{3}x-27=-1
Combine 4x and -\frac{1}{3}x to get \frac{11}{3}x.
\frac{11}{3}x=-1+27
Add 27 to both sides.
\frac{11}{3}x=26
Add -1 and 27 to get 26.
x=26\times \frac{3}{11}
Multiply both sides by \frac{3}{11}, the reciprocal of \frac{11}{3}.
x=\frac{26\times 3}{11}
Express 26\times \frac{3}{11} as a single fraction.
x=\frac{78}{11}
Multiply 26 and 3 to get 78.
