Question

solve x+z=1,y+z=1,x+y=4​ solve fast

Answer 1

Answer:

x = 2 , y = 2 , z = -1

Step-by-step explanation:

We have

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

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

x + y = 4 --- (3)

from (1) ,

x = 1 - z ---(4)

from (2) ,

y = 1 - z  ---(5)

sub x from (4) and y from (5 )in (3) ,

x + y = 4

(1-z)+(1-z) = 4

2 - 2z = 4

- 2z = 4 - 2

z = -1

sub z = -1 in (4) & (5) ,

x = 0

y=0

HENCE , X=2 , Y=2 , Z=-1
