Question

find the value(s) of p. 2x + 3y - 5=0 and px - 6y - 8 =0 if the pair of equation has an unique solution.​

Answer 1

Step-by-step explanation:

when two lines are intersecting then they will have unique solution

so the condition for intersecting lines are

(a1/a2)#(b1/b2)

(2/p)#(3/-6)

3p#-12

p#-12/3

p#-4

that means other than -4 for any value of p, those two lines will intersect and they will have unique solution
