y045y005y 63105 solve for ySolutiony045y005y 63105 solve for

y(.045+y)/.005-y =6.3*10^-5 solve for y

y(.045+y)/.005-y =6.3*10^-5

solve for y

y(.045+y)/(.005-y) =6.3*10^-5

y^2 +0.045y = 6.3*10^-5(0.005 -y)

multiplying both sides by 10^5

100000y^2+ 4500y = 0.0315 - 6.3y

100000y^2 +4506.3y -0.0315 =0

solve the quadratic equation using quadratice formula:

y = (-b +/ -sqrt(b^2 -4ac) )/2a

= ( -4506.3 + /- sqrt( 4506.3^2 + 4*100000*0.0315))/200000

y = 0.0000069 , -0.04507 ( solution )
