Question

Which of the following pairs of linear equations are consistent/inconsistent?If consistent,obtain the solution graphically:
Solve (i) and (iii)​

Answer 1

Answer:

i) consistent ( with infinite solutions )

ii) inconsistent

iii) consistent( with one solution)

iv) inconsistent

Step-by-step explanation:

I) Here,

a1/a2 =b1/b2 = c1/c2

Therefore the lines are coincident, and they will have infinite solutions.

ii) Here,

a1/a2 =b1/b2 ≠ c1/c2

Therefore the lines are parallel, and they will have no solution.

iii) Here,

a1/a2 ≠ b1/b2

Therefore the lines are intersecting , and they will have only one solution.

iv) iii) Here,

a1/a2 = b1/b2 ≠ c1/c2

Therefore the lines are parallel , and they will have no solution.
