8.1%2B3.8h-5.6h=-7.2 Start with the given equation.


10%288.1%2B3.8h-5.6h%29=10%28-7.2%29 Multiply both sides by 10 to clear out the decimals.


81%2B38h-56h=-72 Distribute and multiply.


-18h%2B81=-72 Combine like terms on the left side.


-18h=-72-81 Subtract 81 from both sides.


-18h=-153 Combine like terms on the right side.


h=%28-153%29%2F%28-18%29 Divide both sides by -18 to isolate h.


h=17%2F2 Reduce.
