Question

Solve for x,y and z :x+y=4,y+z=1,z+x=1​

Answer 1

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

Step-by-step explanation:

Rewrite the first equation as

x = 4-y

Now put the value of x in equation third we get

z - y = 1-4

z-y = -3

Now add the second and third equation we get

2z = -2

z = -1

Put the value of z in equation we get

-1 + x = 1

x = 2

And

Similarly

y = 2
