Q25 of 266 Page 3

Solve the following systems of equations:




Multiplying eq1 by 3 and subtracting from eq2


⇒ -11/(x + y) = -1


⇒ x + y = 11 ---------- (3)


Multiplying eq1 by 5 and eq2 by 2 and subtracting


⇒ 15/(x –y) = 3


⇒ x – y = 5 ------ (4)


(3) + (4)


⇒ 2x = 16


⇒ x = 8


Thus, y = 3
