Given set of equations are 

           y=x23x+4                       ...(1)

and     x+y=4     ⇒ y=4x        ...(2)

 

From eq. (1) and (2)

∴ x23x+4=4x

   x22x=0

   x(x2)=0

   x=0  or  2 

 

For x=0 in eq (1)                     For x=2 in eq(1)

⇒ y = 4                                   ⇒ y = 2

 

∴ The solutions are (0,4) and (2,2).
