Решите уравнение: 1) 3(x - 2) = x + 2; 2) 5 - 2(x - 1) = 4 - x; 3) (7x + 1) - (9x + 3) = 5;

1) 3(x - 2) = x + 2 3x - 6 = x + 2 3x - x = 2 + 6 2x = 8 x = 4 2) 5 - 2(x - 1) = 4 - x 5 - 2x + 2 = 4 - x 7 - 2x = 4 - x -2x + x = 4 - 7 -x = -3 x = 3 3) (7x + 1) - (9x + 3) = 5 7x + 1 - 9x - 3 = 5 -2x - 2 = 5 -2x = 7 x = -3,5
