{ 6 * x = 5 * x + 3 - ∫х∫;

- 6 * x = 5 * x + 3 - ∫х∫;

6 * x = - 5 * x + 3 - ∫х∫;

- 6 * x = - 5 * x + 3 - ∫х∫;

{ ∫х∫ = - x + 3;

∫х∫ = 11 * x + 3;

∫х∫ = - 11 * x + 3;

∫х∫ = x + 3;

{ x = - x + 3;

- x = - x + 3;

x = 11 * x + 3;

- x = 11 * x + 3;

x = - 11 * x + 3;

- x = - 11 * x + 3;

x = x + 3;

- x = x + 3;

{x = 3/2;

x = - 3/10;

x = - 1/4;

x = 1/4;

x = 3/10;

x = - 2/3;

Вычислим:

1) 5/8 * ∫0.8∫ + ∫-4.5∫ : 0.3 = 5/8 * 0,8 - 4,5/0,3 = 5/0,1 - 15 = 50 - 15 = 35;

2) 5/12 * ∫ - 4/5∫ + 2.4 : ∫-3,6∫ = - 5/12 * 4/5 - 2,4/3,6 = 1/3 - 2/3 = - 1/3;

3) 0.19 + ∫ - 0.17∫ * 3 - ∫2.4∫ : 6 = 0,19 - 3 * 0,17 - 2,4/6 = 0,19 - 0,51 - 0,4 = - 0,36
