Question

Find value of p of many sol.
(p-3)x+3y=p
px+py-12=0

❤️❤️ i don't understand anyone again sol this que plz.........❤️❤️

Answer 1

Answer:

Step-by-step explanation:

here, a1/a2=(p-3)/p

b1/b2=3/p

c1/c2=p/12

For infinite solutions,we have

a1/a2=b1/b2=c1/c2

from 1st and 2nd terms, we get

p-3/p=3/p

p(p-3)=3p

p2-3p=3p

p2-3p-3p=0

p2-6p=0

p(p-6)=0

p=6

from 2nd &3rd terms we get

3/p=p/12

p2=3×12

p2=36

p=√36

p=6

hope this will help you

Answer 2

ANSWER:-

For many solutions

a1/a2=b1/b2=c1/c2

From these equations

p-3/p=3/p=p/12

p^2-3p-3p=p^2

and 12×3=p^2

=p^2=36

then, p=6
