140x\geq 12600-600
Subtract 600 from both sides.
140x\geq 12000
Subtract 600 from 12600 to get 12000.
x\geq \frac{12000}{140}
Divide both sides by 140. Since 140 is positive, the inequality direction remains the same.
x\geq \frac{600}{7}
Reduce the fraction \frac{12000}{140} to lowest terms by extracting and canceling out 20.
