65+0.8x>109
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
0.8x>109-65
Subtract 65 from both sides.
0.8x>44
Subtract 65 from 109 to get 44.
x>\frac{44}{0.8}
Divide both sides by 0.8. Since 0.8 is positive, the inequality direction remains the same.
x>\frac{440}{8}
Expand \frac{44}{0.8} by multiplying both numerator and the denominator by 10.
x>55
Divide 440 by 8 to get 55.
