Answer: :o I FINALLY MADE IT

(5, 2)

Answer:

x=5\\y=2

Step-by-step explanation:

x^2 +y^2 =29

x+y=7

Solve for x in the second equation.

x+y=7

x+y-y=7-y

x=7-y

Plug in the value for x in the first equation and solve for y.

(7-y)^2 +y^2 =29

y^2-14y+49+y^2 =29

2y^2-14y+20=0

2(y-2)(y-5)=0

2(y-2)=0\\y-2=0\\y=2

y-5=0\\y=5

y

y=2

y\neq 5

Plug y as 2 in the second equation and solve for x.

x+y=7

x=7-y

x=7-2

x=5
