What are the solutions to the simultaneous equation of 2x plus y equals 5 and x squared -y squared equals 3 showing work?
2x + y = 5 . . . thus y = 5 - 2x x2 - y2= 3 . . . . now substitute for y in this equation. x2 - (5 - 2x)2 = 3 . . . and after expansion this becomes, x2 - 25 + 20x - 4x2 = 3 -3x2 + 20x - 28 = 0 . . . and this factors as, (-3x + 14)(x - 2) = 0 Then, x = 2 , x = 14/3 When x = 2, then 2x + y = 5 gives the result y = 1. When x = 14/3 then 2x + y = 5 gives the result y = -13/3.
