a*x + (a + 1)*y = 15
=
$$sqrt{- y^{2} + 9}$$
=
(9 – y^2)^0.5
$$a_{1} = – frac{1}{2 y^{2} – 9} left(y – 15right) left(y – sqrt{- left(y – 3right) left(y + 3right)}right)$$
=
$$- frac{1}{2 y^{2} – 9} left(y – 15right) left(y – sqrt{- left(y – 3right) left(y + 3right)}right)$$
=
-(-15 + y)*(y – (-(3 + y)*(-3 + y))^0.5)/(-9 + 2*y^2)
=
$$- sqrt{- y^{2} + 9}$$
=
-(9 – y^2)^0.5
$$a_{2} = – frac{1}{2 y^{2} – 9} left(y – 15right) left(y + sqrt{- left(y – 3right) left(y + 3right)}right)$$
=
$$- frac{1}{2 y^{2} – 9} left(y – 15right) left(y + sqrt{- left(y – 3right) left(y + 3right)}right)$$
=
-(-15 + y)*(y + (-(3 + y)*(-3 + y))^0.5)/(-9 + 2*y^2)
