Solution

$\frac{6}{7} * \frac{- 3}{13} + \frac{3}{26} - \frac{3}{13} * \frac{8}{7} = \frac{3}{26} - x * 2 \frac{- 18}{91} + \frac{3}{26} - \frac{24}{91} = \frac{3}{26} - 2 x \frac{- 36 + 21 - 48}{182} = \frac{3 - 52 x}{26} \frac{-63}{182} = \frac{3 - 52 x}{26} C r o s s m u l t i p l y - 1638 = 546 - 9464 x - 1638 - 546 = - 9464 x - 2184 = - 9464 x x = \frac{- 2184}{9464} = \frac{3}{13}$

\frac{1}{3} x + y = \frac{10}{3}; 2 x + \frac{1}{4} y = \frac{11}{4}

\frac{5 - \sqrt{3}}{2 + \sqrt{3}} = x + y \sqrt{3}

If $3 x + 7 = 13$ , then $x$ is 2.
