19+5.5h-6.75h=10
Subtract 6.75h from both sides.
19-1.25h=10
Combine 5.5h and -6.75h to get -1.25h.
-1.25h=10-19
Subtract 19 from both sides.
-1.25h=-9
Subtract 19 from 10 to get -9.
h=\frac{-9}{-1.25}
Divide both sides by -1.25.
h=\frac{-900}{-125}
Expand \frac{-9}{-1.25} by multiplying both numerator and the denominator by 100.
h=\frac{36}{5}
Reduce the fraction \frac{-900}{-125} to lowest terms by extracting and canceling out -25.
