Question

The pair of equations 3x+2y+5=0 and -3x-6y+1=0 have
(A) A unique solution
(B) Exactly two solutions
(C) Infinitely many solutions
(D) No solution

Answer 1

Answer:

2 solutions

Step-by-step explanation:

Hope it helps

Answer 2

3x+2y+5 = 0

-3x-6y+1 = 0

Now, a1/a2 = 3/-3 = -1

b1/b2 = 2/-6 = 1/-3

c1/c2 = 5/1 = 5

Here a1/a2 is not equal to b1/b2

Therefore there is a unique solution for the given equations.
