[
x2+y2=1
(x−0.5)2+(y−0.5)2=0.25
]
Isolate xfor x2+y2=1:x=√1−y2,x=−√1−y2
Plug the solutions x=√1−y2,x=−√1−y2 into (x−0.5)2+(y−0.5)2=0.25
For (x−0.5)2+(y−0.5)2=0.25, subsitute x with √1−y2:y=2.5+√1.754,y=2.5−√1.754
For (x−0.5)2+(y−0.5)2=0.25, subsitute x with −√1−y2:No Solution for y∈ℝ
Plug the solutions y=2.5+√1.754,y=2.5−√1.754 into x2+y2=1
For x2+y2=1, subsitute y with 2.5+√1.754:x=√1−8+5√1.7516,x=−√1−8+5√1.7516
For x2+y2=1, subsitute y with 2.5−√1.754:x=√1−8−5√1.7516,x=−√1−8−5√1.7516
Verify solutions by plugging them into the original equations
Therefore, the final solutions for x2+y2=1,(x−0.5)2+(y−0.5)2=0.25 are
