Question 2:
The pair of equations x + 2y + 5 = 0 and – 3x – 6y +1 = 0 has
a) a unique solution
(b) exactly two solutions
( c) infinitely many solutions
(d) no solution

Answer 1

no solution

Step-by-step explanation:

x+2y=-5

multiply by 3

3x+6y=-15. ----equation 3

add equation 2 and 3

gives 0 so no solution

Answer 2

Answer:

no solution

Step-by-step explanation:

it turns out to be a pair of parallel lines. parallel lines donot intersect so no solution.
