We are given the following system of equations:

A solution of the system is the value of "x" for which:

This means the point where the functions yield the same number. To determine if the point:

This means that we need to substitute the value x = 1 and both functions must be equal to 5. Substituting in g(x) we get:

Now we substitute in the function f(x):

Since:

This point is not a solution of the system.
