Question 905206
{{{y^2=100-x^2}}}
{{{y=(2+x)}}}
Substitute (2+x)

{{{(2+x)^2=100-x^2}}}
{{{4+4x+x^2=100-x^2}}}
{{{2x^2+4x-96=0}}}
Divide by 2
{{{x^2+2x-48=0}}}
{{{x=6}}}
{{{x=-8}}}
{{{y=2+6=8}}}
{{{y=2+(-8)=-6}}}
Ans:(6,8) and (-8,-6)

You can also graph it.

{{{ graph( 300, 200, -12, 12, -12, 12, (100-x^2)^(1/2), -(100-x^2)^(1/2), 2+x )}}}
