For which values of p, does the pair of equations given below has unique solution?
3 x + py + 7 = 0 and 4x + 2y + 5 = 0
Answers
Answer:
ANSWER IS HERE ARMY ------
Step-by-step explanation:
Given that,
Two equations, 4x+py+8=0 and 2x+2y+2=0
To find,
The value of p if the pair of equations has a unique solution.
Solution,
The condition for a unique solution is given by :
Here, a₁ = 4, b₁ = p, c₁ = 8 and a₂ = 2, b₂ = 2 and c₂ = 2
Putting the values in in above condition we get :
The value of b is not equal to 4. It means p can take any value other than 4.
Answer:
so here is your answer
Step-by-step explanation:
Given equation:-
4x+py+8=0
a
1
=4,b
1
=p,c
1
=8
2x+2y+2=0
a
2
=2,b
2
=2,c
2
=2
Since the given pair of equation hs unique solution.
Therefore,
a
2
a

=
b

p
⇒p
=4
Hence the given pair of equation has unique solution for all values of p except 4.
