Question 1193266: Solve for y in terms of x.
1.2x+y=8
2.x^2+y^2=25
3.(1/x)+(1/y)=1

You can put this solution on YOUR website!
y=-2x+8, just move x to the other side
-
y^2=25-x^2
y=+/- sqrt(25-x^2)
-
(1/x)+(1/y)=1
y+x=xy, multiplying through by xy
y-xy=-x
y(1-x)=-x
y=-x/(1-x) or x/(x-1), x NE 0 , y NE 0
