$\bf \left \{{{14x - 11y = 29}} \atop{13y - 8x = 30} \right.$

$\bf \left \{{{x = \frac{29}{14} + \frac{11}{14} y }} \atop{13y - 8 x = 30} \right.$

$\bf13y - 8( \frac{29}{14} + \frac{11}{14} y) = 30$

$\bf{y = \frac{326}{47} }$

$\bf{x = \frac{29}{14} + \frac{11}{14} \times \frac{326}{47} }$

$\bf{x = \frac{707}{94} }$

$\boxed{ \bf(x,y) = ( \frac{707}{94} , \frac{326}{47}) }$
