Решение уравнений
Задача 1
- x - 2 = -3x\[x + 3x = 2\]\[4x = 2\]\[x = \frac{2}{4}\]\[x = \frac{1}{2} = 0.5\]
- -2x - 4 = 3x\[-2x - 3x = 4\]\[-5x = 4\]\[x = -\frac{4}{5} = -0.8\]
- -x - 7 = x\[-x - x = 7\]\[-2x = 7\]\[x = -\frac{7}{2} = -3.5\]
- -3x - 9 = 2x\[-3x - 2x = 9\]\[-5x = 9\]\[x = -\frac{9}{5} = -1.8\]
- -4x - 9 = 6x\[-4x - 6x = 9\]\[-10x = 9\]\[x = -\frac{9}{10} = -0.9\]
- -2x - 7 = -4x\[-2x + 4x = 7\]\[2x = 7\]\[x = \frac{7}{2} = 3.5\]
- -8x - 3 = -6x\[-8x + 6x = 3\]\[-2x = 3\]\[x = -\frac{3}{2} = -1.5\]
Задача 2
- 8 + 7x = 9x + 4\[7x - 9x = 4 - 8\]\[-2x = -4\]\[x = \frac{-4}{-2} = 2\]
- -5 + 9x = 10x + 4\[9x - 10x = 4 + 5\]\[-x = 9\]\[x = -9\]
- -4 + 7x = 8x + 1\[7x - 8x = 1 + 4\]\[-x = 5\]\[x = -5\]
- 9 + 8x = 6x - 2\[8x - 6x = -2 - 9\]\[2x = -11\]\[x = -\frac{11}{2} = -5.5\]
- -1 - 3x = 2x + 1\[-3x - 2x = 1 + 1\]\[-5x = 2\]\[x = -\frac{2}{5} = -0.4\]
- -4 - 6x = 4x - 3\[-6x - 4x = -3 + 4\]\[-10x = 1\]\[x = -\frac{1}{10} = -0.1\]
- 1 - 10x = 5x + 10\[-10x - 5x = 10 - 1\]\[-15x = 9\]\[x = -\frac{9}{15} = -\frac{3}{5} = -0.6\]
- 7 + 8x = -2x - 5\[8x + 2x = -5 - 7\]\[10x = -12\]\[x = -\frac{12}{10} = -1.2\]
- 2 + 3x = -7x - 5\[3x + 7x = -5 - 2\]\[10x = -7\]\[x = -\frac{7}{10} = -0.7\]
- -5 + 2x = -2x - 3\[2x + 2x = -3 + 5\]\[4x = 2\]\[x = \frac{2}{4} = \frac{1}{2} = 0.5\]
