ok so first set them equal to each other
[tex]3x + 2x + 2 = 5x + 5[/tex]
now combine the x's on the left
[tex]5x + 2 = 5x + 5[/tex]
next to get rid of one on the x's you's have to move one of the 5's to the other side and subtract. keaving you with
[tex]2 = 5[/tex]
there are no x's so therefore there is no solutuon :)
