No solutions means that the values of x in both sides of the equal sign don't match with each other. 

For example:
2x + 3 = 2x + 5
2x - 2x + 3 = 2x - 2x + 5
3 = 5 <--- that's not true

calculusxy · Answer

Just solve for the x's in both sides of the equal sign for each equation. Whichever ones have x's that don't match, then you know that there is no solution.
