Answer:
1/2h+9=17
We move all terms to the left:
1/2h+9-(17)=0
Domain of the equation: 2h!=0
h!=0/2
h!=0
h∈R
We add all the numbers together, and all the variables
1/2h-8=0
We multiply all the terms by the denominator
-8*2h+1=0
Wy multiply elements
-16h+1=0
We move all terms containing h to the left, all other terms to the right
-16h=-1
h=-1/-16
h=1/16
Ratio: 15:9
