Question

solve by cramer's rule ​

Answer 1

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

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

x + z = 0 ------------------------(3)

From Eqn. (3) x = -z

now putting x = -z in (1)

y - z = -1 ---------------------------(4)

adding (2) and (4)

y = 0

Hence, z = 1 and x = -1
