-4k>-1
Subtract 1 from both sides. Anything subtracted from zero gives its negation.
k<\frac{-1}{-4}
Divide both sides by -4. Since -4 is negative, the inequality direction is changed.
k<\frac{1}{4}
Fraction \frac{-1}{-4} can be simplified to \frac{1}{4} by removing the negative sign from both the numerator and the denominator.
