Answer:
by subtracting bother equation we will get
-7/y = -7 thus y = 1

Bhai samajh nhi aaaya
dekho, do alag equation Diya hua hai, dono ko jab ghatayenge to 1/x Kat jayega kyonki dono same hai, bacha -4/y aur -3/y (minus is liye ki ghatane ke bad sign badal jata hai) ko aapas main jor Diya
itna karne ke bad = ke dahine taraf 2 aur -9 ko ghata Diya aur sign minus ka laga diya
ab humare pas -7/y = -7 bacha to ise solve karne pe y = 1 mila
ab y = 1 ko equation 1/x +3/y = 2 main dalo to hame x ka man milega,
simple
