215-3x-4x<0
Subtract 4x from both sides.
215-7x<0
Combine -3x and -4x to get -7x.
-7x<-215
Subtract 215 from both sides. Anything subtracted from zero gives its negation.
x>\frac{-215}{-7}
Divide both sides by -7. Since -7 is negative, the inequality direction is changed.
x>\frac{215}{7}
Fraction \frac{-215}{-7} can be simplified to \frac{215}{7} by removing the negative sign from both the numerator and the denominator.
