-4x<-2-5
Subtract 5 from both sides.
-4x<-7
Subtract 5 from -2 to get -7.
x>\frac{-7}{-4}
Divide both sides by -4. Since -4 is negative, the inequality direction is changed.
x>\frac{7}{4}
Fraction \frac{-7}{-4} can be simplified to \frac{7}{4} by removing the negative sign from both the numerator and the denominator.
