Question

solve the system of equation by usingcramers rule x+y+z=6,x-y+z=2,x+2y-z=2​

Answer 1

I found x is 1 y is 2 and z is 3

Step-by-step explanation:

1. 1+2+3 is 6

2.1-2+3

1+3-2

4-2

2

3. 1+2*2-3

1+4-3

5-3

2

Answer 2

x=1,y=2,z=3

1.

x+y+z=6

1+2+3=6

6=6

0=0

2.

x-y+z=2

1-2+3=2

-1+3=2

2=2

0=0

3. x+2y-z=2

1+2*2-3=2

1+4-3=2

1+1=2

2=2

0=0
