Answer:


Step-by-step explanation

X+Y=2 , 2X-Y=1

x+y=1 , 2(x)-y=1

put,

    'x' = a

   'y' = b

a+b=2 × 2  ⇒ 2a+2b=4    ⇔1

2a-b=1      ⇒  2a-b=1        ⇔2

                      3b=3

                      b=3\3

                      b=1

put  b in 1

a+b=2

a+1=2

a=2-1

a=1

              put,                                       put,  

            x=a                                          y=b

            x=1                                          y=1
