11/75 = x/65.....11 in. to 75 lbs. = x in. to 65 lbs.
cross multiply
(75)(x) = (65)(11)
75x = 715
x = 715/75
x = 9.53 rounds to 9.5 <==

The steps below show the incomplete solution to find the value of x for the equation
mafiozo [28]
Step 1: 6x - 2x - 5 = -6 + 21 
Step 2: 6x - 2x - 5 = 15 
Step 3: 4x - 5 = 15 

The next step would be to add 5 to both sides of the equation. 
so Step 3: 4x - 5 = 15 .......add 5 to both sides would make 
Step 4: 4x = 20 
 
So after the next step you would have 4x = 20 

Hope this helps! :)
