What are the solutions of the equation f (x) = g(x)?

We have the following functions:
 f (x) = 2 ^ x - 2
 g (x) = 3x - 3
 To find the next result f (x) = g (x) the first thing that you should observe is the table so that values of x both functions have the same result.
 We observe that the values are:
 x = 1
 x = 3
 
 the solutions of the equation f (x) = g (x) are:
 x = 1
 x = 3
