Пошаговое объяснение

$1) x+2\frac{3}{13} =10\frac{8}{39} \\x=\frac{398}{39} -\frac{29}{13} \\x=\frac{311}{39} \\x=7\frac{38}{39}$

$2) y+8\frac{7}{12} =10\frac{5}{24} \\y=\frac{245}{24} -\frac{103}{12} \\y=\frac{245-206}{24} \\y=\frac{39}{24} =1\frac{15}{24} =1\frac{5}{8}$

$3) x+14\frac{2}{9} =38\frac{1}{18} \\x=\frac{685}{18} -\frac{128}{9}\\x=\frac{685-256}{18} \\x=\frac{429}{18} =23\frac{15}{18} =23\frac{5}{6}$

$4) y+3\frac{7}{11} =9\frac{3}{22}\\y=\frac{201}{22}-\frac{40}{11} \\y=\frac{201-80}{22} \\y=\frac{121}{22} =\frac{11}{2}=5\frac{1}{2}$
