Answer 2

$a)x + 1 \frac{7}{9} = 2 \frac{4}{9} \\ x = 2 \frac{4}{9} - 1 \frac{7}{9} \\ x = \frac{22}{9} - \frac{16}{9} \\ x = \frac{6}{9} = \frac{2}{3} \\ b)3 \frac{5}{8} - x = 1 \frac{3}{8} \\ - x = 1 \frac{3}{8} - 3 \frac{5}{8} \\ - x = \frac{11}{8} - \frac{29}{8} \\ - x = \frac{18}{8} \\ x = \frac{9}{4}$
