Answer: No solutions.
============================================
Work Shown:
4c + 5 < 4c + 3
4c+5-4c < 4c+3-4c ... subtract 4c from both sides
4c-4c+5 < 4c-4c+3
0c+5 < 0c+3
0+5 < 0+3
5 < 3 ... statement is false
Since that statement is false, this means the original inequality is false regardless of what you pick for c.
There are no solutions.
