# Math Help - Rational Function

1. ## Rational Function

Solve

1) $1/x-1 + 1/x = 5$

2) $3x/x^3+x = 5$

3) $4x/x-1 = 6$

It will be appreciated if you explained by steps, so I can write it on my notes. I really need help with this, please help!

Thank you

This would imply

$4-1 = 6$

which makes no sense.

Did you mean?

$\frac{4x}{x-1} = 6$

if so

Spoiler:

$4x = 6(x-1)$

$4x = 6x-6$

$-2x = -6$

$x = 3$
