Answer by ewatrrr(10682)   (Show Source): You can put this solution on YOUR website! ``` Hi 2x+5y+z=22 3x-3y-z=-22 5x+y+2z=-3 Solving by elimination 2x+5y+z=22 3x-3y-z=-22 5x + 2y = 0 6x-6y+2z=-44 5x+y+2z=-3 11x - 5y = -47 5x + 2y = 0 11x - 5y = -47 25x + 10y = 0 22x - 10y = -94 47x = -94 x = -2 and y = 5 ( 5x + 2y = 0, y = -5x/2= 10/2) AND z = 22-2x-5y = 1 ```
