7.5x>100-10
Subtract 10 from both sides.
7.5x>90
Subtract 10 from 100 to get 90.
x>\frac{90}{7.5}
Divide both sides by 7.5. Since 7.5 is positive, the inequality direction remains the same.
x>\frac{900}{75}
Expand \frac{90}{7.5} by multiplying both numerator and the denominator by 10.
x>12
Divide 900 by 75 to get 12.
