Answer 1

Answer:

let the given equations be no.1, no.2.

Now add both of them you get an equation.after subtract it you get another equation.

Now solve both ,,you get the values of x,y...

HOPE THIS IS USEFULL TO YOU.........

THANK U......

Answer 2

Answer:

x=0 y=-1

Step-by-step explanation:

(x-2)(y-1)=xy

xy-x-2y+2=xy

x+2y-2=0. - eq1

(x-1)(y+1)=xy

xy+x-y-1=xy

x-y-1=0. -eq2

EQ 1 - Eq2

x-2y-2-(x-y-1)=0

-y-1=0

y=-1

x-2*(-1)-2=0

x=0
