Ismai aap infinite solutions wali condition laga dena a1/a2=b1/b2=c1/c2....then in dono equations se ye values is condition mai rakh dena...a1= p-3, b1=3, c1= p, a2= p, b2= p, c2= 12....then jab ye values isi condition mai rakhoge na toh ye milega (p-3)/p = 3/p = p/12 and then...inn mai se koi bhi do le lena...jaise aapne liya b1/b2=c1/c2 jo hai 3/p = p/12 then cros multiply kr dena u will get p^2= 36 then p= √30 therefore p=6....

They have infinite solutions...therefore a1/a2= b1/b2.........so (p-3)/p=3/p.......p-3=3......so we get p=6
