The equation |2x+a|=|b-x| has exactly 2 solutions, at x=-4 and x=2/3. Find the value(s) of a and b. Ok so the questions is asking me to find possible values of a and b which make the equation true for ONLY x=-4 and x=2/3. So for: |a-8|=|b+4| |a+4/3|=b-2/3| I need to find the values of a and b that satisfy both equations. Its from there im a little stuck. Any help would be greatly appreciated. Thanks in advance, Dan.
