1.х+2 $\frac{7}{16}$ =5 $\frac{3}{16}$
х=5 $\frac{3}{16}$ -2 $\frac{7}{16}$
х= $\frac{83}{16}$ - $\frac{39}{16}$
х= $\frac{44}{16}$ =2 $\frac{75}{100}$ =2 $\frac{3}{4}$
2.4 $\frac{5}{14}$ -(х-7 $\frac{3}{14}$ )=2 $\frac{9}{14}$
х- 7 $\frac{3}{14}$ =4 $\frac{5}{14}$ -2 $\frac{9}{14}$
х-7 $\frac{3}{14}$ = $\frac{59}{14}$ - $\frac{37}{14}$
х-7 $\frac{3}{14}$ = $\frac{22}{14}$
х=7 $\frac{3}{14}$ + $\frac{22}{14}$
х= $\frac{101}{14}$ + $\frac{22}{14}$
х= $\frac{123}{14}$
