Question

Solve this system of equation algebracally y+x=19-x2 x+y=80

Answer 1

Answer:

The answer is  y = 80±$\sqrt{61} i$ and    x = ± $\sqrt{61} i$

Step-by-step explanation:

   We need to solve this system of equations algebraically

   y + x = 19  - $x^{2}$ ..............................................(1)

   x+y = 80 ...............................................................................(2)

   Substituting equation (2) in equation  (1)

   80 = 19 -  $x^{2}$

   -61 = $x^{2}$

   x = ± $\sqrt{61} i$

   Where i is the imaginary

  Then the value of y = 80±$\sqrt{61} i$

   This is the solution to this system of equations
