$\frac{3}{4} x - \frac{4}{9} = \frac{7}{18} x - \frac{2}{3}$ $3/4x-4/9=7/18x-2/3$

$\frac{7}{18} x - \frac{3}{4} x = - \frac{4}{9} + \frac{2}{3}$ $7/18x-3/4x=-4/9+2/3$

$\frac{14}{36} x - \frac{27}{36} x = - \frac{4}{9} + \frac{6}{9}$ $14/36x-27/36x=-4/9+6/9$

$- \frac{13}{36} x = \frac{2}{9}$ $-13/36x=2/9$

$x = \frac{\frac{2}{9}}{- \frac{13}{36}}$ $x=(2/9)/(-13/36)$

$x = - \frac{72}{117}$ $x=-72/117$
