Please help me to solve each rational equations.

A. Solve each RATIONAL EQUATIONS.
[tex]1. \: \frac{1}{x} = \frac{2}{3x - 1} [/tex]
[tex]2. \: \frac{1}{x} + \frac{1}{2x} = \frac{2}{3} [/tex]

B. Find the DOMAIN of the following.
[tex]1. \: f(x) = \frac{x}{1 + 3x} [/tex]
[tex]2. \: g(x) = \frac{2 {x}^{2} - x + 1 }{x + 2} [/tex]
[tex]3. \: h(x) = \frac{5x + 15}{3x + 15} [/tex]
[tex]4. \: f(x) = \frac{4}{ {x}^{2} - 9} [/tex]
[tex]5. \: k(x) = \frac{1}{x - 6} [/tex]



Thank you! This would be a big help for me since sobrang hina ko sa math :((
