No, x & y are a undefined number, thanks to you Daniel, I may not fail my math test tomorrow. But don't you need to divide out the 3?
So, subtract 3x from both sides to solve for x? 5y=15-3y?
Yes, a relatively simple problem (as said by my math teacher) but I can't figure out the formula/our teacher thought we would know this from 7th grade. (which I don't)
If someone could explain the formula for this sort of problem, it would greatly be appreciated.
Oh and I'm new here.
