How to solve linear equations by substitution

Well, if we know y, we can now solve for x. x is equal to 9 minus 2y. So let's do that. x is equal to 9 minus 2 times y, 2 times 7. Or x is equal to 9 minus 14, or x is equal to negative 5. So we've just, using substitution, we've been

What students say

It's peefect it's very helpful on god, the operation is super easy and i had no trouble entering the formulas, otherwise it is super perfect, because in my area,using it online is not always suitable ( i mean using wifi ) except cellular data, very reliable, the student can't provide much money to subscribe we here to download to help us to understand math instead of helping they do that for business.

I simply love this app 🤩❤😍🥰. The minute i saw this on an advert i knew this was going to help me. This is a great app, sometimes it doesn't scan the problem correctly but you just have to double check if it is correct and if it isn't then just rescan, but this app has helped a lot.
