-\frac{1}{9}x-\frac{1}{9}\left(-27\right)+\frac{1}{3}\left(x+3\right)=x+67
Use the distributive property to multiply -\frac{1}{9} by x-27.
-\frac{1}{9}x+\frac{-\left(-27\right)}{9}+\frac{1}{3}\left(x+3\right)=x+67
Express -\frac{1}{9}\left(-27\right) as a single fraction.
-\frac{1}{9}x+\frac{27}{9}+\frac{1}{3}\left(x+3\right)=x+67
Multiply -1 and -27 to get 27.
-\frac{1}{9}x+3+\frac{1}{3}\left(x+3\right)=x+67
Divide 27 by 9 to get 3.
-\frac{1}{9}x+3+\frac{1}{3}x+\frac{1}{3}\times 3=x+67
Use the distributive property to multiply \frac{1}{3} by x+3.
-\frac{1}{9}x+3+\frac{1}{3}x+1=x+67
Cancel out 3 and 3.
\frac{2}{9}x+3+1=x+67
Combine -\frac{1}{9}x and \frac{1}{3}x to get \frac{2}{9}x.
\frac{2}{9}x+4=x+67
Add 3 and 1 to get 4.
\frac{2}{9}x+4-x=67
Subtract x from both sides.
-\frac{7}{9}x+4=67
Combine \frac{2}{9}x and -x to get -\frac{7}{9}x.
-\frac{7}{9}x=67-4
Subtract 4 from both sides.
-\frac{7}{9}x=63
Subtract 4 from 67 to get 63.
x=63\left(-\frac{9}{7}\right)
Multiply both sides by -\frac{9}{7}, the reciprocal of -\frac{7}{9}.
x=\frac{63\left(-9\right)}{7}
Express 63\left(-\frac{9}{7}\right) as a single fraction.
x=\frac{-567}{7}
Multiply 63 and -9 to get -567.
x=-81
Divide -567 by 7 to get -81.
