How do you solve the system of equations #9y + 4x - 11= 0# and #3y + 10x + 31= 0#?
We have the equations:
Multiply the second equation by
Now we can subtract the second equation from the first equation. This leaves:
Now plug this into one of the original equations. I like small numbers so I'll plug into the second equation:
