\frac{8}{9}-3^{2}x=\frac{49}{67}
Divide both sides by 67.
\frac{8}{9}-9x=\frac{49}{67}
Calculate 3 to the power of 2 and get 9.
-9x=\frac{49}{67}-\frac{8}{9}
Subtract \frac{8}{9} from both sides.
-9x=\frac{441}{603}-\frac{536}{603}
Least common multiple of 67 and 9 is 603. Convert \frac{49}{67} and \frac{8}{9} to fractions with denominator 603.
-9x=\frac{441-536}{603}
Since \frac{441}{603} and \frac{536}{603} have the same denominator, subtract them by subtracting their numerators.
-9x=-\frac{95}{603}
Subtract 536 from 441 to get -95.
x=\frac{-\frac{95}{603}}{-9}
Divide both sides by -9.
x=\frac{-95}{603\left(-9\right)}
Express \frac{-\frac{95}{603}}{-9} as a single fraction.
x=\frac{-95}{-5427}
Multiply 603 and -9 to get -5427.
x=\frac{95}{5427}
Fraction \frac{-95}{-5427} can be simplified to \frac{95}{5427} by removing the negative sign from both the numerator and the denominator.
