-x=\frac{11}{14}-\frac{8}{9}
Subtract \frac{8}{9} from both sides.
-x=\frac{99}{126}-\frac{112}{126}
Least common multiple of 14 and 9 is 126. Convert \frac{11}{14} and \frac{8}{9} to fractions with denominator 126.
-x=\frac{99-112}{126}
Since \frac{99}{126} and \frac{112}{126} have the same denominator, subtract them by subtracting their numerators.
-x=-\frac{13}{126}
Subtract 112 from 99 to get -13.
x=\frac{13}{126}
Multiply both sides by -1.
