How do you solve #|x - 1| = |2x + 2|#?
so the solution set is
Because this expression involves absolute values there are at least two solutions for the value of
How come? We are given:
And we know that since there are absolute values involved there will be at least one positive and one negative expression to be calculated. In this case there are two absolute values so let's try all the possibilities.
To arrive at two answers for the solution of
