Bài 2: Tìm x, biết:
1) \( 2(x+5) - 4x = 1 \)
2) \( 3(x-2) + 2(x-3) = 5 \)
3) \( x(5-2x) + 2x(x-1) = 13 \)
4) \( 3x\left(\frac{4}{3}\right) - 4x(x-2) = 10 \)
5) \( 5(x^3 - 3x + 1) + x(1 - 5x) = x - 2 \)
6) \( 12x^2 - 4x(3x - 5) = 10x - 17 \)
7) \( 6x^2 - (2x + 5)(3x - 2) = -12 \)
8) \( (x-3)(x+3) - x(x-5) = 1 \)
9) \( 4(2 - x) + x(x + 6) = x^2 \)
10) \( x(x - 7) - (x - 2)(x + 5) = 0 \)
