If aq is not equal to bp then the system of equations, ax + by = c and px + qy= r have :
Answers
Answer:
the following system of equation has a unique solution.
Step-by-step explanation:
ax+by=c
px+qy=r
so, a1/a2=a/p
b1/b2= b/q
and, c1/c2= c/r
it is given that
aq≠bp
so, a/p≠b/q
this means that a1/a2≠b1/b2
thus the equation has a unique solution.
If aq ≠ bp then system of equations ax + by = c and px + qy = r have unique solution
Correct question : If aq ≠ bp then system of equations ax + by = c and px + qy = r have
Given :
The system of equations ax + by = c and px + qy = r
To find :
The number of solutions when aq ≠ bp
Concept :
For the given two linear equations
Consistent :
One of the Below two condition is satisfied
1. Unique solution :
2. Infinite number of solutions ( coincident lines) :
Inconsistent :
No solution
Solution :
Solution :Step 1 of 2 :
Write down the given system of equations
Here the given system of equations are
ax + by = c - - - - - (1)
px + qy = r - - - - - (2)
Step 2 of 2 :
Find number of solutions when aq ≠ bp
Comparing with the equation
a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0 we get
a₁ = a , b₁ = b , c₁ = - c and a₂ = p , b₂ = q , c₂ = - r
Now it is given that
So the system of equations ax + by = c and px + qy = r have unique solution
