\[1)\ 3\frac{7}{24} + x = 5\]

\[x = 5 - 3\frac{7}{24}\]

\[x = 4\frac{24}{24} - 3\frac{7}{24}\]

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

\[Ответ:1\frac{17}{24}.\]

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

\[x = 1 - 0,52\]

\[x = 0,48\]

\[Ответ:0,48.\]

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

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

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

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

\[Ответ:7\frac{2}{7}.\]

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

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

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

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

\[Ответ:4\frac{6}{9}.\]

\[5)\ (234 + x) - 456 = 178\]

\[234 + x = 178 + 456\]

\[234 + x = 634\]

\[x = 634 - 234\]

\[x = 400\]

\[Ответ:400.\]

\[6)\ (x - 4,83) + 0,16 = 3,02\]

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

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

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

\[x = 7,69\]

\[Ответ:7,69.\]

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

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

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

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

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

\[Ответ:9\frac{2}{3}.\]

\(8)\ 5,2 - (6 - y) = 3,258\)

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

\[y = 6 - 1,942\]

\[y = 4,058\]

\[Ответ:4,058.\]
