Respuesta :

it should be -2,4 or -5,1.


since both answers = y then you put them equal to each other and then solved for x.


x+6=x^2 +8x +16
0=x^2 +7x +10
0=(x+2)(x+5)

x=-2 or -5


and for y I input the two separately into one of the equations

y= (-2)+6

y=4


y=(-5)+6

y=1


and then I double checked by imputing my y's and x's  into the remaining equation.


(4)=(-2)^2 +8(-2)+16
4=4-16+16
4=4


(1)=(-5)^2 +8(-5)+16
1=25-40+16
1=1

I hope your tests go well with the help of this knowledge.
