Expand everything, then you will be able to cancel xy in both equations. The system will be a linear one.
worldly onyx
yes but im still left with x, y
deep wave
Yes. But both equations are linear, so it's easy to solve the system.
You can use any method you like: Gauss, Kramer, substitution, etc.

Tysm
deep wave
You're welcome!
worldly onyx
I'm sorry, I totally forgot how to keep on from here. I got to a simply equation of 6x+5y=21 after expanding and simplifying it
@deep wave Idk if im allowed to do that but if you're still around
I've only heard of Gauss but isn't it for another type of equations?
deep wave
I've only heard of Gauss but isn't it for another type of equations?
Well, Gauss's method works for any linear systems.
What equations did you get when you expanded and simplified?
deep wave
Why just one? There should be two equations.
worldly onyx
Because after expanding I subtracted the two equations and got this
so I could get rid of xy
deep wave
You can't just get rid of one of the equations.
worldly onyx
Sry for the bad hand writing
Oh
Mind showing a way to solve it? If not too much to ask
I've been on it for too long I should've gotten an answer to that, I usually work on harder equations
deep wave
After expanding and simplifying, you get this:
2x - 3y = -19
2x - y = -1
worldly onyx
Omg i understand sorry
deep wave
Here the simplest way to do this would be to subtract the first equation from the second, then the first one will contain only y.
