Question

I just need x isolated

Answer 1

x=-y+
`\sqrt{`y^2+4rt/2r

Step-by-step explanation:

solve using the quadratic equation

Answer 2

`x=(-y+√(y^2+4rt) )/(2r)`

`x=(-y-√(y^2+4rt) )/(2r)`

Step-by-step explanation:

`rx+y=(t)/(x)\\\\x(rx+y)=((t)/(x))x\\\\rx^2+yx=t\\\\rx^2+yx-t=t-t\\\\rx^2+yx-t=0`

Solve using the quadratic formula.

`x=(-y+√(y^2+4rt) )/(2r)`

`x=(-y-√(y^2+4rt) )/(2r)`
