+1218 Find all $c$ such that $|c + 5| - 3|c + 7| = 10 + 2|c - 8|.$ Enter all the solutions, separated by commas.
+129845 There is a (messy) algebraic solution, but a graph works better
The left hand side is represented by the lower graph and the right hand side is represented by the upper graph..
The graphs do not intersect, so there is no "c" that makes the two sides of the equations equal....
