Question

The solution set of x-y+2z=5, 2x+y-z=1, 3x-2y+3z=8 is

Answer 1

Answer:

x=1,y=2,z=3

Step-by-step explanation:

x-y+2z=5  ----------------(1)

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

3x-2y+3z=8 --------------(3)

Add (1) and (2)

3x+z=6  ---------------(4)

4x+2y-2z = 2 ----------(5) = (2)*2

Add (5) and (3)

7x+z=10 --------------(6)

(6) - (4)

4x=4

x=1

z=3

y=2
