Question 927526
{{{y=-x/3+5/3}}}
-
{{{x^2+(-x/3)+5/3)^2=25}}}
{{{x^2+x^2/9-x*5/3-x*5/3+25/9=25}}}
{{{x^2+x^2/9-10x/3=25-25/9}}}
{{{9x^2+x^2-30x=25*9-25}}}
{{{10x^2-30x=200}}}
{{{x^2-3x=20}}}
{{{x^2-3x-20=0}}}
-
{{{x=(3+- sqrt(9+4*20))/2}}}
{{{highlight(x=(3+- sqrt(89))/2)}}}, and use this to evaluate y.
