Answer 1

$15 frac{4}{7} - 4 frac{3}{8} times (1 frac{3}{7} - x) = 13 frac{14}{7} \ frac{60}{7} - frac{3}{2} times ( frac{3}{7} - x) = frac{52}{7} \ frac{60}{7} - frac{9}{14} + frac{3}{2}x = frac{52}{7} \ frac{111}{14} + frac{3}{2}x = frac{52}{7} \ 111 + 24x = 104 \ 21x = 104 - 111 \ 21x = - 7 \ x = - frac{1}{3}$
