Answer 1

==========================

Answer 2

$3x + \frac{11}{9} = x + \frac{6}{4} \\ \\ 3x + \frac{11}{9} = \frac{3}{2} \\ \\ 3x = x + \frac{3}{2} - \frac{11}{9} = x + \frac{5}{18} \\ \\ 3x - x = \frac{5}{18} \\ \\ 2x = \frac{5}{18} \\ \\ x = \frac{ \frac{5}{18} }{2} = \frac{5}{18 \times 2} = \frac{5}{36}$
