2. Решите уравнение: a) 4(2x-3)-5(3x - 2) = 9x-26 6) 17x-(4x + 3) = 3x + 2 B) | 2x+7 | =5

2. Решите уравнение:

a) $$4(2x-3)-5(3x - 2) = 9x-26$$

$$8x - 12 - 15x + 10 = 9x - 26$$

$$-7x - 2 = 9x - 26$$

$$-7x - 9x = -26 + 2$$

$$-16x = -24$$

$$x = \frac{-24}{-16} = \frac{3}{2} = 1.5$$

Ответ: $$x = 1.5$$

б) $$17x-(4x + 3) = 3x + 2$$

$$17x - 4x - 3 = 3x + 2$$

$$13x - 3 = 3x + 2$$

$$13x - 3x = 2 + 3$$

$$10x = 5$$

$$x = \frac{5}{10} = 0.5$$

Ответ: $$x = 0.5$$

в) $$| 2x+7 | =5$$

1) $$2x + 7 = 5$$

$$2x = 5 - 7$$

$$2x = -2$$

$$x = -1$$

2) $$2x + 7 = -5$$

$$2x = -5 - 7$$

$$2x = -12$$

$$x = -6$$

Ответ: $$x_1 = -1, x_2 = -6$$
