5\times 18+7-18\left(x-\frac{2\times 18+5}{18}\right)=1\times 18+11
Multiply both sides of the equation by 18.
90+7-18\left(x-\frac{2\times 18+5}{18}\right)=1\times 18+11
Multiply 5 and 18 to get 90.
97-18\left(x-\frac{2\times 18+5}{18}\right)=1\times 18+11
Add 90 and 7 to get 97.
97-18\left(x-\frac{36+5}{18}\right)=1\times 18+11
Multiply 2 and 18 to get 36.
97-18\left(x-\frac{41}{18}\right)=1\times 18+11
Add 36 and 5 to get 41.
97-18x-18\left(-\frac{41}{18}\right)=1\times 18+11
Use the distributive property to multiply -18 by x-\frac{41}{18}.
97-18x+41=1\times 18+11
Multiply -18 times -\frac{41}{18}.
138-18x=1\times 18+11
Add 97 and 41 to get 138.
138-18x=18+11
Multiply 1 and 18 to get 18.
138-18x=29
Add 18 and 11 to get 29.
-18x=29-138
Subtract 138 from both sides.
-18x=-109
Subtract 138 from 29 to get -109.
x=\frac{-109}{-18}
Divide both sides by -18.
x=\frac{109}{18}
Fraction \frac{-109}{-18} can be simplified to \frac{109}{18} by removing the negative sign from both the numerator and the denominator.
