Question

check wether the following pair of linear equation is consisting if yes solve it graphically 2x-5y=0, x+y=0

Answer 1

YES, 2x-5y=0, x+y=0 is constant

BECAUSE WE ONLY ONE CASE IS INCONSISTENCE

WHEN A1/A2=B1/B2 NOT EQUAL TO C1/C2

WHEN EQUATION ARE PARREL THEN

THE EQUATION IS INCONSISTENCE

BUT THERE ARE A1/A2 IS NOT EQUAL TO B1/B2

==> 2/1 IS NOT EQUAL TO  -5/1

SO, ITS HAVE UNIQUE SOLUTION

SO, THAT EQUATION IS INCOSISTENCE

I HOPE ITS HELPFUL

Answer 2

Answer:

12. a) Using matrix inversion method, solve the following system of

equations:

2x - y+3z=1.

x+y+z=2,

(or)

x-y+2=4
