Question

Which of the following pair of linear equations are

consistent

A) x+y+3=0 B) x+2y+3=0 C) 2x-y-5=0 D) 3x+6y=12

2x+2y+2=0 x-2y-3=0 4x-2y+2=0 x+2y-6=0​

Answer 1

Answer:

B.) x+2y+3=0

x-2y+3=0

Step-by-step explanation:

Consistent solution means there are solutions of these equations.

means it should satisfy

either,

a1/a2is not equal to b1/b2(unique solution)

or

a1/a2 =b1/b2=c1/c2(infinite solutions)

or we can say that,

it shouldn't be

a1/a2=b1/b2 is not equal to c1/c2(no solutions)

so,option is consistent
