The equation is saying x minus 7 is greater than -6, so treat the inequality symbol just how you would with a normal =. So x-7=-6, you need to find x, so to find x you need to keep x alone. So you get rid of the -7, so to do that since it is a negative you add 7 to -6, so that would mean that x=1. Now you put the inequality symbol back. So now it's x>1. This is the solution, x is greater than 1, or x>1. Hope this helps
