1) \(4\frac{5}{23} + x = 10\frac{2}{23}\)
\(x = 10\frac{2}{23} - 4\frac{5}{23}\)
\(x = 9\frac{25}{23} - 4\frac{5}{23}\)
\(x = 5\frac{20}{23}\)
2) \(7\frac{9}{16} - (x - 2\frac{3}{16}) = 4\frac{11}{16}\)
\(7\frac{9}{16} - x + 2\frac{3}{16} = 4\frac{11}{16}\)
\(9\frac{12}{16} - x = 4\frac{11}{16}\)
\(x = 9\frac{12}{16} - 4\frac{11}{16}\)
\(x = 5\frac{1}{16}\)
3) \(\frac{29}{34} - \frac{x}{34} = \frac{12}{34}\)
\(29 - x = 12\)
\(x = 29 - 12\)
\(x = 17\)
