149x-330y=-511 --------eq 1 -330x+149y=-32 --------eq 2 Subtract eq 2 from eq 1, we get, 479x-479y=-479 By removing common we get, x-y=-1 ---------eq 3 Add eq 2 in eq 1 we get, -181x-181y=-543 By removing common we get, x+y=3---------eq 4 By elimination method, Subtract eq 4 from eq 3 we get, x=2 By putting the value of x in eq 4 we get, y=1 So the value of x= 2and y= 1
