7x+4 (2x - 7) + 4=1-2 (5x-3) + 5

Найдем корень уравнения.

7 * x + 4 * (2 * x - 7) + 4 = 1 - 2 * (5 * x - 3) + 5;

Раскроем скобки.

7 * x + 4 * 2 * x - 4 * 7 + 4 = 1 - 2 * 5 * x + 2 * 3 + 5;

7 * x + 8 * x - 28 + 4 = 1 - 10 * x + 6 + 5;

7 * x + 8 * x - 24 = - 10 * x + 10;

15 * x - 24 = - 10 * x + 10;

15 * x + 10 * x = 10 + 24;

x * (15 + 10) = 24;

x * 25 = 24;

25 * x = 24;

x = 24/25.
