Use elimination to solve the system of equations. -2x+y+3z=20 -3x+2y+z=21 3x-2y+3z=-9 A. x = -4, y = -3, z = 3 B. x = 4, y = 3, z = 4 C. x = 4, y = -3, z = 5 D. x = -4, y = 3, z = 3
What terms can you kill off right off the bat?
@Geometry_Hater why do you hate Geometry ??
Because it sucks
i'm guessing 2y?
Yes because they are opposites Anything else up there like that?
