Answer 1

Answer:

:(

Step-by-step explanation:

sorry no answer

Answer 2

Step-by-step explanation:

1 2 1. 6

2 1 2. 6

1 1 1. 5

R2-2R1 & R3-R1

1 2 1. 6

0 -3 0. 6

0 -1 0. -1

R3- R2/3

1 2 1. 6

0 -3 0. -6

0 0 0. 1

r(A)=2. r(A|B)=3. number of variable=3

r(A)=r(A|B)=n ===unique solution

r(A)=r(A|B)<n ===infinte no. of solution.

r(A)=/r(A|B). ==== no solution...

that's why given equation have no solution.
