I think the question is asking, when x=1 what if f of x or the y value. It appears to be a simply addition problem. Just plug the value in and sum up the total

You are not Solving for variable 'f'. f is not a variable. f(x) is a function

substitute the x value (in our case it is 1) into the equation for x and solve.
