X => 5  ; Y=>2

Step-by-step explanation:

***************  HEY DEAR  ***************

HERE IS YOUR ANSWER.......

       X + Y = 7   .......................  (1.)

      X - Y = 3   ........................  (2.)

ADD EQUATION (1.) AND (2.)

 2X = 10

X=> 5 .................................. ANS.

PUT THIS VALUE IN (1.) EQUATION..

     Y => 7 - 5

     Y => 2 ........................ ANS.

Answer 2

x-y = 3

x = 3+y

------------

x+y = 7

3+y + y =7

3 + 2y = 7

2y = 7-3

y = 4÷2 = 2 Ans





Now,

x - y = 3

x - 2 = 3

x = 3+2=5 Ans...
