-9w=\frac{23}{28}-\frac{5}{6}
Subtract \frac{5}{6} from both sides.
-9w=\frac{69}{84}-\frac{70}{84}
Least common multiple of 28 and 6 is 84. Convert \frac{23}{28} and \frac{5}{6} to fractions with denominator 84.
-9w=\frac{69-70}{84}
Since \frac{69}{84} and \frac{70}{84} have the same denominator, subtract them by subtracting their numerators.
-9w=-\frac{1}{84}
Subtract 70 from 69 to get -1.
w=\frac{-\frac{1}{84}}{-9}
Divide both sides by -9.
w=\frac{-1}{84\left(-9\right)}
Express \frac{-\frac{1}{84}}{-9} as a single fraction.
w=\frac{-1}{-756}
Multiply 84 and -9 to get -756.
w=\frac{1}{756}
Fraction \frac{-1}{-756} can be simplified to \frac{1}{756} by removing the negative sign from both the numerator and the denominator.
