Giving 20 points and ! solve for x. y=7x-7z-9

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

Google it that might work
