-4x>-12-3
Subtract 3 from both sides.
-4x>-15
Subtract 3 from -12 to get -15.
x<\frac{-15}{-4}
Divide both sides by -4. Since -4 is negative, the inequality direction is changed.
x<\frac{15}{4}
Fraction \frac{-15}{-4} can be simplified to \frac{15}{4} by removing the negative sign from both the numerator and the denominator.
