Question 339658
{{{8.1+3.8h-5.6h=-7.2}}} Start with the given equation.



{{{10(8.1+3.8h-5.6h)=10(-7.2)}}} Multiply both sides by 10 to clear out the decimals.



{{{81+38h-56h=-72}}} Distribute and multiply.



{{{-18h+81=-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=(-153)/(-18)}}} Divide both sides by {{{-18}}} to isolate {{{h}}}.



{{{h=17/2}}} Reduce.

Answer:


So the solution is {{{h=17/2}}}
