Answer:
x= 15
Step-by-step explanation:
We can use cross products to solve this problem
7 2x+5
-- = --------
3 x
7x = 3(2x+5)
Distribute
7x = 6x +15
Subtract 6x from each side
7x-6x = 6x-6x+15
x = 15
By iteratively substituting, we have



and the pattern continues down to the first term
,



Recall the formulas


It follows that



3/4=12/16
12/16 is greater than 11/16
