Bài 2: Tìm x biết

1) \( 3 - 2\sqrt{x} = -1 \)
2) \( 3\sqrt{x} + 1 = 40 \)
3) \( 2 - 3\sqrt{x} = -7 \)
4) \( \frac{2}{5} - \sqrt{x} = \frac{1}{4} \)
5) \( \sqrt{x} + \frac{1}{3} = \frac{5}{12} \)
6) \( \frac{1}{6} + \sqrt{x} = \frac{5}{12} \)
7) \( \frac{7}{\sqrt{x} - 6} = 2 \)
8) \( \frac{8}{\sqrt{x} + 5} = 9 \)
9) \( \frac{9}{\sqrt{x} + 1} = 1 \)
10) \( \frac{10}{\sqrt{2x} - 3} = 7 \)
11) \( \frac{11}{\sqrt{3x} - 7} = 5 \)
12) \( \frac{12}{\sqrt{2} - 3x} = 4 \)
