2.4x+3.8-2.9x>1.75
Subtract 2.9x from both sides.
-0.5x+3.8>1.75
Combine 2.4x and -2.9x to get -0.5x.
-0.5x>1.75-3.8
Subtract 3.8 from both sides.
-0.5x>-2.05
Subtract 3.8 from 1.75 to get -2.05.
x<\frac{-2.05}{-0.5}
Divide both sides by -0.5. Since -0.5 is negative, the inequality direction is changed.
x<\frac{-205}{-50}
Expand \frac{-2.05}{-0.5} by multiplying both numerator and the denominator by 100.
x<\frac{41}{10}
Reduce the fraction \frac{-205}{-50} to lowest terms by extracting and canceling out -5.
