Question

Question 5. Find whether the following pair of linear equations is consistent or inconsistent: (2015) 3x + 2y = 8 6x – 4y = 9​

Answer 1

Answer:

this is the correct answer

Answer 2

Solution:-

a₁ = 3 and a₂ = 6

b₁ = 2 and b₂ = - 4

c₁ = 8 and c₂ = 9

a₁/a₂ = 3/6 = 1/2

b₁/b₂ = 2/-4 = 1/-2

c₁/c₂ = 8/9

Since, a₁/a₂ ≠ b₁/b₂ or 1/2 ≠ 1/-2, hence the following pair of linear equation is consistent.
