Question

Solve the following system of equations graphically 2x + y = 2 =x - y = 1

Answer 1

This equation can be written as
2x+y =2....(1)
x-y =1........(2)
on adding these both equations (1) and (2) we get 3x =3
i.e x=1 ...(since y and -y will be cancelled out )
so now put the value of x in any of the equation..
u will get y = 0
Hope it helps u out ..
