Bài 2. Tìm x, biết:

a) \( x + \frac{5}{3} = -\frac{1}{3} \);
b) \( x + \frac{5}{5} = \frac{5}{5} \);
c) \( 2 - \frac{4}{23} - 11 + 29 = 2 \);
d) \( H = \frac{15}{28} + 28 + 15 - 27 \);
e) \( \frac{1}{12} - \frac{3}{4} = 2 \);
f) \( 4 - \frac{3}{5} = -1 \);
g) \( k = \frac{1 - 5}{-3 - 5} - 2 + 3 \);
h) \( \frac{9}{2} [3 - (x - 7)] = -5 \);
i) \( 7 - (x + 5) = -12 \);
j) \( 1 = \frac{-1 + 3 - 5}{5} \);
k) \( \frac{16}{21} [16 - (5 - 21)] = 5 \).
