35r-21+35r<19
Add 35r to both sides.
70r-21<19
Combine 35r and 35r to get 70r.
70r<19+21
Add 21 to both sides.
70r<40
Add 19 and 21 to get 40.
r<\frac{40}{70}
Divide both sides by 70. Since 70 is positive, the inequality direction remains the same.
r<\frac{4}{7}
Reduce the fraction \frac{40}{70} to lowest terms by extracting and canceling out 10.
