4. Реши уравнения: 1) -1 1/3 x + 1/3 = x - 2; 2) 19 - 2(3x + 8) = 2x - 37; 3) (3x - 1)/2 = (x - 2)/3

1) $$- \frac{4}{3}x + \frac{1}{3} = x - 2$$
$$-4x + 1 = 3x - 6$$
$$7 = 7x$$
$$x = 1$$
2) $$19 - 6x - 16 = 2x - 37$$
$$3 - 6x = 2x - 37$$
$$40 = 8x$$
$$x = 5$$
3) $$3(3x - 1) = 2(x - 2)$$
$$9x - 3 = 2x - 4$$
$$7x = -1$$
$$x = -1/7$$
