f%28x%29=%283x%2B4%29%2F%282x-A%29 Start with the given equation.


f%280%29=%283%280%29%2B4%29%2F%282%280%29-A%29 Plug in x=0


2=%283%280%29%2B4%29%2F%282%280%29-A%29 Now plug in f%280%29=2


2=%280%2B4%29%2F%280-A%29 Multiply


2=-4%2FA Combine like terms and simplify


2A=-4 Multiply both sides by A.


A=-4%2F2 Divide both sides by 2.


A=-2 Reduce.


So the solution is A=-2
