Question

The pair of equations x +2y + 5 = 0 and 3x-6y + 1 = 0 have
a) Infinitely many solution b) no solution
c) a unique solution d) exactly two solution​

Answer 1

Answer:

unique solution

Step-by-step explanation:

when solved, you get a single value of X and y

Answer 2

Answer:

c]

Step-by-step explanation:

x+2y+5=0,x-6y+1=0

A1=1

A2=1

B1=2

B2=-6

C1=5

C2=1

A1/A2=1/1=1

B1/B2=2/6=1/3

A1/A2 is not equal to B1/B2 hence these lines are intersecting and they have a unique solution
