x+5+x+1+x=3(x+2)+1

1)x=0

2)x=3

3)no solution

4) infinite

I got #3 no solution

x+5+x+1+x=3(x+2)+1

x+5+x+1+x=3x+6+1

3x+6=3x+7

-3x -3x

6=7 so no solution

Is this correct?

Thanks for checking over my work.

If your x's drop out and you end up with a false statement, such as our 6 = 7, then there is NO solution

if, however, the x's drop out and you end up with a true statement, there would have been an infinite number of solutions.
