Question

pair of linear equations is consistent or not x+y= 14 x-y=4​

Answer 1

Answer:

yes consistent

as A1/A2is not equal to B1/B2

Answer 2

Answer:

CONSISTENT

Step-by-step explanation:

x+y=14

x+y-14=0 -------1 (a1=1, b1=1 , c1=-14)

x-y=4

x-y-4=0 --------2 (a2=1, b2=-1, c2=-4)

a1/a2 b1/b2 c1/c2

1/1 1/-1 -14/-4

1/1 -1/1 7/2

Therefore, a1/a2 is not equal to b1/b2

Therefore, it is consistent.
