Question 1175207

Hi
 {{{xy = -30}}}  0r y = -30/x
 x + y = -1      Or {{{y = -x-1}}}
 x + -30/x +1 = 0
 x^2 + x - 30 = 0
 (x+6)(x - 5) = 0 
 x = 5  0r x = -6
 y = -6 Or y = 5
 P(5,-6) and  P(-6,5) are the solutions for this System of Equations
 y = -30/x  and y = -x - 1
{{{drawing(300,300,    -10,10,-10,10,   
 grid(1),
circle(5, -6,0.4),
circle(-6,5,0.4),

Wish You the Best in your Studies.
