Answer 1

$1) \: 3 \frac{7}{24} + x = 5 \\ x = 5 - 3 \frac{7}{24} = 1 \frac{17}{24} \\ 2) \: x + 0.52 = 1 \\ x = 0.48 \\ 3) \: y - 5 \frac{3}{7} = 1 \frac{7}{6} \\ y = 1 \frac{7}{6} + 5 \frac{3}{7} \\ y = \frac{13}{6} + \frac{38}{7} \\ y = \frac{91 + 228}{42} \\ y = \frac{319}{42} =7 \frac{25}{42} \\ 4) \: y - 4.25 = 3.75 \\ y = 3.75 + 4.25 = 8 \\ y = 8 \\ 5) \: 8 \frac{4}{9} - m = 3 \frac{7}{9} \\ m = 8 \frac{4}{9} - 3 \frac{7}{9} \\ m = 4 \frac{6}{9} \\ 6) \: 2 - x = 1.376 \\ x = 2 - 1.376 \\ x = 0.624 \\ 7) \: (234 + x) - 456 = 178 \\ 234 + x = 178 + 456 \\ 234 + x = 634 \\ x = 634 - 234 \\ x = 400$
