Решите уравнение: 2 - 3(2 + 3x) = 14 5(x - 3.6) = 9x -5x = 11 - 2(4x - 2) 10(2 - x) + 11x = -3x 7x - 15 = 4x - 3(x - 3)

1. 2 - 3(2 + 3x) = 14 2 - 6 - 9x = 14 -4 - 9x = 14 -9x = 18 x = -2 2. 5(x - 3.6) = 9x 5x - 18 = 9x -18 = 4x x = -4.5 3. -5x = 11 - 2(4x - 2) -5x = 11 - 8x + 4 -5x = 15 - 8x 3x = 15 x = 5 4. 10(2 - x) + 11x = -3x 20 - 10x + 11x = -3x 20 + x = -3x 4x = -20 x = -5 5. 7x - 15 = 4x - 3(x - 3) 7x - 15 = 4x - 3x + 9 7x - 15 = x + 9 6x = 24 x = 4
