You just solve this like you would an other equation. I'm going to just put > for this problem.
So we have: 7x-10>16.
Add 10 to get x by itself: 7x>26.
But x isn't by itself so we have to divide by 7. This isn't going to come out even because we're dividing an even by an odd, but: x>26/7
So x>3.714... or x>26/7. Both are correct.
