54\left(\frac{2\times 9+5}{9}-x\right)+2\times 18+11=2\left(1\times 9+4\right)
Multiply both sides of the equation by 18, the least common multiple of 9,18.
54\left(\frac{18+5}{9}-x\right)+2\times 18+11=2\left(1\times 9+4\right)
Multiply 2 and 9 to get 18.
54\left(\frac{23}{9}-x\right)+2\times 18+11=2\left(1\times 9+4\right)
Add 18 and 5 to get 23.
54\times \frac{23}{9}-54x+2\times 18+11=2\left(1\times 9+4\right)
Use the distributive property to multiply 54 by \frac{23}{9}-x.
\frac{54\times 23}{9}-54x+2\times 18+11=2\left(1\times 9+4\right)
Express 54\times \frac{23}{9} as a single fraction.
\frac{1242}{9}-54x+2\times 18+11=2\left(1\times 9+4\right)
Multiply 54 and 23 to get 1242.
138-54x+2\times 18+11=2\left(1\times 9+4\right)
Divide 1242 by 9 to get 138.
138-54x+36+11=2\left(1\times 9+4\right)
Multiply 2 and 18 to get 36.
174-54x+11=2\left(1\times 9+4\right)
Add 138 and 36 to get 174.
185-54x=2\left(1\times 9+4\right)
Add 174 and 11 to get 185.
185-54x=2\left(9+4\right)
Multiply 1 and 9 to get 9.
185-54x=2\times 13
Add 9 and 4 to get 13.
185-54x=26
Multiply 2 and 13 to get 26.
-54x=26-185
Subtract 185 from both sides.
-54x=-159
Subtract 185 from 26 to get -159.
x=\frac{-159}{-54}
Divide both sides by -54.
x=\frac{53}{18}
