Question

3. Find whether the following pair of linear equations is consistent or
inconsistent:
y-x=1 ; x - 3y = 4​

Answer 1

Answer:

Consistent pair of equations.

Step-by-step explanation:

y-x=1                                        x-3y=4

-x+y-1=0                                   x-3y-4=0

Here,                                        Here,

a₁=-1                                         a₂=1

b₁=1                                          b₂=-3

c₁=-1                                         c₂=-4

a₁/a₂=-1                b₁/b₂=-1/3            c₁/c₂=1/4

Since a₁/a₂≠b₁/b₂

This is consistent and has a unique value.
