Multiply the second equation by 2, then subtract the two equations. That will eliminate the x's
Oh lol yeah solve the system of equations and then tell what the coordinates are of the solution that lies in quadrant 3
wouldn't you multiply the second equation by -2?
I thought we did this one together
No they arent the same
they are exactly the same
But I have another thing to ask and I dont feel like opening another question so can someone help? What conic section does this equation represent? 9x^2+4y^2+18x=16
how is this system 2x^2+y^2=33 x^2+y^2+2y=19 different from this system 2x^2+y^2=33 x^2+y^2+2y=19?
Maybe they are the same but I really need the practice and the question was different
no it wasn't
but I'm done arguing
You can multiply the second equation by -2
