Solve the equations 1. X + y + 5 = 0 2. XY + 14 = 0 x = y=

Solve the equations 1. X + y + 5 = 0 2. XY + 14 = 0 x = y=

x+y=-5
xy=-14
Then x.y class is regarded as two roots of the equation x ^ 2 + 5x-14 = 0. Just remove the roots of the equation. Note that there are two groups of solutions, x = 7, y = - 2 or x = - 2, y = 7
