what is the answer po
y2+5x+4
y2-3x-4


Sagot :

y is equal to positive negative one, and x is equal to negative 1

[tex] y^{2} [/tex] + 5x = 4 and [tex] y^{2} [/tex] -3x -4  
multiply negative to the second equation, so as to cancel the y squared, then you will have : 
[tex] y^{2} [/tex] + 5x = 4 and -[tex] y^{2} [/tex] +3x +4  
simply add them, giving you: 
8x+8=0, solve for x, giving you -1  

substitute -1 to the x of any equation, solve for it, then y= positive negative 1
