Question

if x+z=4 , y+z=2 , x+y=0 then find the value of x by using Crammers rule is msq​

Answer 1

Step-by-step explanation:

x + z = 4.........(1)

x+y=0

x = - y..........(2)

y+z=2........(3)

put the value of equation 2 in 1

we get,

z - y = 4......(4)

put the value of y from euq. (4) in (3)

we get,

z - 4 + z = 3

2z = 7

z = 7/2

put this in (1)

x + 7/2 = 4

x = 4-7/2

x = 1/2
