Let's find
f(x) = 2, which is essentially what the problem is asking, what
x corresponds to an output of 2.


Let's solve below:


f(x) = 2

  • Setting up what we know


23x + 4 = 2

  • Substituting in
    23x + 4 for
    f(x) (I'm not sure if this is the correct expression for
    f(x) due to formatting issues)


23x = -2

  • Subtract 4 from both sides to make a step to isolate
    x (what we are trying to find)


x = - (2)/(23)

  • Divide both sides of the equation by 23 to isolate
    x

Thus the input is
\boxed{x = - (2)/(23)}.
