ASAP need help with system of equations... I'm too small brain to do it.
navik [9.2K]

Answer:

(x=0, y=11)

(x=2, y=9)

Step-by-step explanation:

first equation substitution for x first.

y=11-x

plug into 2nd equation

(x+2)^2+(11-x-7)^2=20

this should lead you into a quadratics equation.

you get x=0, x=2.

do the same for y value this time, subbing in the x value

(11-y+2)^2+(y-7)^2=20

this also leads into a quad equation

solve and you get y=11, and y=9
