Simutaneous equation by substitution:y+2x=0,4x+y=3..................solve for x and y

Sagot :

1y + 2x = 0 ⇒ -2x - 1y = 0
4x + 1y = 3 ⇒  4x + 1y = 3
                                2x = 3
                                 2     2
                                  x = 1.5
                     4(1.5) + y = 3
                            6 + y = 3
                         - 6        - 6
                                  y = -3
                            (x, y) = (1.5, -3)
