Question

Find the value of p for which the following pair of linear equations has exactly one solution ;
9x + py - 1 = 0
3x + 4y -2 = 0

Answer 1

Answer:

12

Step-by-step explanation:

Given:

9x+py-1=0

3x+4y-2=0

To have exactly one solution, the condition is,

a1/a2=b1/b2

=> 9/3=p/4

=> 9*4= 3p

=> 36=3p

=> 36/3=p

=> 12=p

p=12

Hope this helps you to understand easier....
