Gauss Elimation
1) 7x-4y-2z=-6
2)16x+2y+z=3​

Answer 1

Answer:

Elimination was used to solve a system of equations. One of the intermediate steps led to the equation 9x=27 . Which of the following systems could have led to this equation? 4x+3y=24 −5x−3y=3 7x−2y=15 x+y=6 9x+2y=21 −9x−2y=21 10x−y=15
