Question

what value of P will the following pair of linear equations have infinitely many solutions (P - 3) x + 3 Y = p and p x + p Y =12

Answer 1

Answer:

Step-by-step explaination:

givrn,(p-3)x+3y=p and px+py=12

Acc to the given condition,

a1/a2=b1/b2=c1/c2

therfore:(p-3)/p=3/p=p/12

(p-3)/p=3/p

》p2-3p=3p

p2=6p》p=6

to check this answer put the value of p in 3/p=p/12.You get,LHS=RHS
