How do you solve x+2y=5 and 2x-3y=-4?
Ok. So prefer the elimination method, but you can do this with substitution as well.
First put the equations on top of each other
Then find the variable that would be easiest to cancel out. I think it's
Now let's add the two equations together!
Now we simply divide by -7 to get
But wait! We're not done!
which simplifies to
So we subtract 4 from both sides, and get
Hope this helps!
