We just need to see everything that is not x as a number.
if I asked
we would solve it by combining like terms first. but, if I tell you not to do that, we would add 9 and 7(2) to both side and end up with
we would then divide both sides by 7
math is always math... it's just how we look at it. so, do the same steps!
add 9 and 7z to both side
divide both sides by 7
