-90000+150a>75000
Subtract 150000 from 60000 to get -90000.
150a>75000+90000
Add 90000 to both sides.
150a>165000
Add 75000 and 90000 to get 165000.
a>\frac{165000}{150}
Divide both sides by 150. Since 150 is positive, the inequality direction remains the same.
a>1100
Divide 165000 by 150 to get 1100.
