\[x = 1\frac{17}{24}\]

\[Ответ:1\frac{17}{24}.\]

\[2)\ x + 0,52 = 1\]

\[x = 1 - 0,52\]

\[x = 0,48\]

\[Ответ:0,48.\]

\[3)\ y - 5\frac{3}{7} = 1\frac{6}{7}\]

\[y = 1\frac{6}{7} + 5\frac{3}{7}\]

\[y = 6\frac{9}{7}\]

\[y = 7\frac{2}{7}\]

\[Ответ:7\frac{2}{7}.\]

\[4)\ y - 4,25 = 3,75\]

\[y = 3,75 + 4,25\]

\[y = 8\]

\[Ответ:8.\]

\[5)\ 8\frac{4}{9} - m = 3\frac{7}{9}\]

\[m = 8\frac{4}{9} - 3\frac{7}{9}\]

\[m = 7\frac{13}{9} - 3\frac{7}{9}\]

\[m = 4\frac{6}{9}\]

\[Ответ:4\frac{6}{9}.\]

\[6)\ 2 - x = 1,376\]

\[x = 2 - 1,376\]

\[x = 0,624\]

\[Ответ:0,624.\]

\[7)\ (234 + x) - 456 = 178\]

\[234 + x = 178 + 456\]

\[234 + x = 634\]

\[x = 634 - 234\]

\[x = 400\]

\[Ответ:400.\]

\[8)\ (x + 13,216) - 24,83 = 5,17\]

\(x + 13,216 = 5,17 + 24,83\)

\[x + 13,216 = 30\]

\[x = 30 - 13,216\]

\[x = 16,784\]

\[Ответ:16,784.\]

\[9)\ (x - 4,83) + 0,16 = 3,02\]

\[x - 4,83 = 3,02 - 0,16\]

\[x - 4,83 = 2,86\]

\[x = 2,86 + 4,83\]

\[x = 7,69\]

\[Ответ:7,69.\]

\[10)\ \left( x - 1\frac{8}{23} \right) + 3\frac{19}{23} = 5\frac{12}{23}\]

\[x - 1\frac{8}{23} = 5\frac{12}{23} - 3\frac{19}{23}\]

\[x = 4\frac{35}{23} - 3\frac{19}{23} + 1\frac{8}{23}\]

\[x = 2\frac{35 - 19 + 8}{23}\]

\[x = 2\frac{24}{23} = 3\frac{1}{23}\]

\[Ответ:3\frac{1}{23}.\]

\[11)\ (8164 - x) - 2398 = 2557\]

\[8164 - x = 2557 + 2398\]

\[8164 - x = 4955\]

\[x = 8164 - 4955\]

\[x = 3209\]

\[Ответ:3209.\]

\[12)\ (20 - a) - 6\frac{7}{18} = 3\frac{17}{18}\]

\[20 - a = 3\frac{17}{18} + 6\frac{7}{18}\]

\[20 - a = 9\frac{24}{18} = 10\frac{6}{18}\]

\[a = 20 - 10\frac{1}{3}\]

\[a = 9\frac{2}{3}\]

\[Ответ:9\frac{2}{3}.\]

\[13)\ 0,8 - (x - 0,326) = 0,495\]

\[x - 0,326 = 0,8 - 0,495\]

\[x - 0,326 = 0,305\]

\[x = 0,305 + 0,326\]

\[x = 0,631\]

\[Ответ:0,631.\]

\[14)\ 1,2 - \left( x - \frac{1}{4} \right) = \frac{1}{2}\]

\[x - 0,25 = 1,2 - 0,5\]

\[x = 0,7 + 0,25\]

\[x = 0,95\]

\[Ответ:0,95.\]

\[15)\ 7000 - (5210 - x) = 4569\]

\[5210 - x = 7000 - 4569\]

\[x = 5210 - 2431\]

\[x = 2779\]

\[Ответ:2779.\]

\(16)\ 5,2 - (6 - y) = 3,258\)

\[6 - y = 5,2 - 3,258\]

\[y = 6 - 1,942\]

\[y = 4,058\]

\[Ответ:4,058.\]

\(17)\ 80 - (x + 4,097) = 18,36\)

\[x + 4,097 = 80 - 18,36\]

\[x = 61,64 - 4,097\]

\[x = 57,543\]

\[Ответ:57,543.\]

\[18)\ 12 - \left( x + 4\frac{7}{15} \right) = 5\frac{13}{15}\]

\[x + 4\frac{7}{15} = 12 - 5\frac{13}{15}\]

\[x = 10\frac{30}{15} - 5\frac{13}{15} - 4\frac{7}{15}\]

\[x = 1\frac{30 - 13 - 7}{15} = 1\frac{10}{15}\]

\[x = 1\frac{2}{3}\]

\[Ответ:1\frac{2}{3}.\]
