45t-45-20t>0
Subtract 20t from both sides.
25t-45>0
Combine 45t and -20t to get 25t.
25t>45
Add 45 to both sides. Anything plus zero gives itself.
t>\frac{45}{25}
Divide both sides by 25. Since 25 is positive, the inequality direction remains the same.
t>\frac{9}{5}
Reduce the fraction \frac{45}{25} to lowest terms by extracting and canceling out 5.
