4500x+1500-4800x>0
Subtract 4800x from both sides.
-300x+1500>0
Combine 4500x and -4800x to get -300x.
-300x>-1500
Subtract 1500 from both sides. Anything subtracted from zero gives its negation.
x<\frac{-1500}{-300}
Divide both sides by -300. Since -300 is negative, the inequality direction is changed.
x<5
Divide -1500 by -300 to get 5.
