Question

7. The pair of equations x + 2y + 5 = 0 and 3x + 6y +1=0 has
solutions.​

Answer 1

Step-by-step explanation:

x+2y+5=0

x+2y= -5

x= -5-2y

x= -7y

and

3x+6y+1=0

3x+6y= -1

3x= -1-6y

3x= -7y

x= -7y/3

Answer 2

Answer:

The pair of equations x+2y+5=0 and -3x-6y+1=0 has. Hence , the pair of equations has no solution.
