(1). 2x - y = 4
y - z = 6
x - z = 10​

Answer 1

Answer:

the correct answer is there

please give me award for this one

Step-by-step explanation:

ANSWER

We have,

2x−y=4 ..(i)

y−z=6 ..(ii)

x−z=10 ..(iii)

From equation (iii), we get z=x−10

Substituting the value of z in equation (ii), we get

y−(x−10)=6

⇒−x+y=−4 ...(iv)

Adding equations (i) and (iv), we get

x=0

Putting x=0 equation in (i) and (iii) we get

y=−4 and z=−10

Hence, x=0,y=−4,z=−10 is the solution of the given system of equations.
