9-8k=0
Calculate 3 to the power of 2 and get 9.
-8k=-9
Subtract 9 from both sides. Anything subtracted from zero gives its negation.
k=\frac{-9}{-8}
Divide both sides by -8.
k=\frac{9}{8}
Fraction \frac{-9}{-8} can be simplified to \frac{9}{8} by removing the negative sign from both the numerator and the denominator.
