1)10x-4x=2,226 3)7x-10,36=6,512)6x+2x+2,352=4,2 4)4,42-14x=3,3

Вычислим корешки уравнений.

1) 10 * x 4 * x = 2,226;

Вынесем за скобки х.

x * (10 4) = 2.226;

x * 6 = 2.226;

6 * x = 2.226;

x = 2.226/6;

x = 0.371.

3) 7 * x - 10,36 = 6,51;

Приведем к виду a * x = b.

7 * x = 6.51 + 10.36;

7 * x = 16.87;

x = 16.87/7;

x = 2.41.

2) 6 * x + 2 * x + 2,352 = 4,2;

Приведем сходственные.

x * (6 + 2) + 2.352 = 4.2;

x * 8 + 2.352 = 4.2;

8 * x = 4.2 2.352;

8 * x =  1.848;

x = 1.848/8;

x = 0.231.

4) 4,42 14 * x = 3,3;

-14 * x = 3.3 4.42;

-14 * x = -1.12;

14 * x = 1.12;

x = 1.12/14;

x = 0.08.
