Question

x+y+z=1,2x+y+z=2,x+2y+2z=1
please answer it its urgent ​

Answer 1

Step-by-step explanation:

x+y + z = 1 --------------(1)

2x +y + z = 2 ----------(2)

x + 2y + 2z = 1 --------- (3)

(2) => ( x + y + z) + x = 2

=> 1 + x = 2 (from 1)

=> x = 2-1

=> x = 1

putting x =1 in (1) we get

1+ y +z = 1

=> y + z =0

=> y = -z

so, x =1 and y = -z or z = -y
