X+y+z=63x−2y+2z=2−2x−y+3z=−4 Enter your answer, in the form (x, y,z), in the boxes in simplest terms.

Evaluate

x+y+z, then set it equal to −4.=−4

Step-by-step explanation:

(2 , 3, 1)

Step-by-step explanation:

x + y + z = 6   ..(1)

3x - 2y + 2z = 2   ..(2)

-2x - y + 3z = -4  ..(3)

(1)*3-(2): 5y + z = 16  ..(4)

(1)*2+(3): y + 5z = 8  ..(5)

(4)*5-(5): 24y = 72         y = 3

(4): 5*3 + z = 16              z = 1

(1): x + y + z = x + 3 + 1 = 6        x = 2

2x^2+5x+17
