Question

Check whether pair of equation 5x-y=7 and x-y=-1 are consistent or not

Answer 1

yes because a1/a2 not equal to b1/b2

Answer 2

Answer:

Step-by-step explanation:

5x-y=7

x-y=-1

Clearly a1 is not equal to b1

a2 b2

a1 = 5 b1= -1

a2= 1 b2=-1

It would have 1 solution Therefore, the pair of equation is consistent .
