Answer:
y = 
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 
when x = 
, thus
= 
= 2k ( divide both sides by 2 )
k = 
y = 
← equation of variation
When x = 
, then
y = 
= 
=
Plug 7 into each y. 9(7) -4(7) +3
63-28+3
The answer is 38
