Answer:
10+12.50h=5+15h
We move all terms to the left:
10+12.50h-(5+15h)=0
We add all the numbers together, and all the variables
12.50h-(15h+5)+10=0
We get rid of parentheses
12.50h-15h-5+10=0
We add all the numbers together, and all the variables
-2.5h+5=0
We move all terms containing h to the left, all other terms to the right
-2.5h=-5
h=-5/-2.5
h=+2
