Solve each equation for \(x\).
\[ d = f + fx \]
Answer (2)
d = f + f x f + f x = d ∣ s u b t r a c t f f ro m b o t h s i d es f x = d − f ∣ d i v i d e b o t h s i d es b y f x = f d − f o t h er an s w er : x = f d − f = f d − f f x = f d − 1
To solve the equation d = f + f x for x , rearrange it to isolate x yielding x = f d − f or x = f d − 1 . Both forms provide the correct solutions. Remember to assume that f = 0 when dividing.
