ax+9y=5 and 4x+by=3 are the equation of two parallel line then minimum value of a+b is
Yes the ans can be negative too. Anyway the mod of the answer has to be 12.
Its not necessary that a and b are positive.
So the min. Value can be negative.
This answer is my way. I dont know if thw method is correct.
Is there a better way to solve it? Please do tell me.
Which means ab = 36
Now we get minimum if the 2 numbers are 6 and 6
its 13 ...
A.M.is greater or equal to G.M.
