0.85x-0.75x<50
Subtract 0.75x from both sides.
0.1x<50
Combine 0.85x and -0.75x to get 0.1x.
x<\frac{50}{0.1}
Divide both sides by 0.1. Since 0.1 is positive, the inequality direction remains the same.
x<500
Expand \frac{50}{0.1} by multiplying both numerator and the denominator by 10. Anything divided by one gives itself.
