Question

the pair of equation x+2y+5=0 and _3x_6y+1 =0 has​

Answer 1

Answer:

x+2y+5=0

-3x-6y+1=0

a1=1

b1=2

c1=5

a2=-3

b2=-6

c2=1

a1/a2=-1/3

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

c1/c2=5/1 =5

since,

a1/a2=b1/b2≠ c1/c2

therefore, the equations has

no solution

lines are parallel

Answer 2

Answer:

we can say that

x/3x=2y/6y=5/1

-1/3=-1/3=5/1

so above a1/a2=b1/b2(not equal to)=/c1/c2

the above lines are parallel lines..

the equation have no solution...
