To solve this absolute value equation, we can use find the solutions as follows taking into account the definition of absolute value, then, we have:
Now, we can solve both equations to find the solution(s):
First case:
Second case:
Then, both solutions are the same, because of the absolute rule (this is the point when y = 0, that is the x-intercept for this function.)
Therefore, the solution set is {19/20}.
