MCQ - 352-9084

Question:

The pair of linear equations 6x - 3y + 10 = 0, 2x - y + 9 = 0 has

one solution
two solutions
many solutions
two solutions

Correct Answer: D

Explanation:

Comparing the equation with the set of equations
a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0
we have,
a₁= 6, a₂ = 2
b₁ = -3, b₂ = -1
c₁ = 10, c₂ = 9
and we have,

So, we have

and in this case, we know that equations have no solution.
