Can anyone help me out? got some algebra 2..

OpenStudy (anonymous):

What is the solution set to the following set? x+y=4 x^2 + y^2=16

rishavraj (rishavraj):

see its x + y = 4 on squaring both sides \[\(x \+\ y)\^\2\ \=\ \1\6\\] so x^2 + y^2 + 2xy = 16

rishavraj (rishavraj):

and u r given tht x^2 + y^2 = 16 i.e the second equation so u get 2xy = 0

rishavraj (rishavraj):
