Решите уравнение:2х+14=6, 9х-18=27, 8х+12=20, 15х-10=5, 9х+15=6, 8х-6=14

Найдем корешки.

1) 2 * х + 14 = 6; 

2 * x + 14 = 6;

2 * x + 14 = -6;

2 * x = 6  - 14;

2 * x = -6 - 14;

2 * x = -8;

2 * x = -20;

x = -8/2;

x = -20/2;

x = -4;

x = -5.

2) 9 * х - 18 = 27; 

9 * x  - 18 = 27;

9 * x - 18 = -27;

9 * x = 45;

9 * x = 9;

x = 5;

x = 1.

3) 8 * х + 12 = 20; 

8 * x = 20 - 12;

8 * x = -20 - 12;

8 * x = 8;

8 * x = -32;

x = 1;

x = -4.

4) 15 * х - 10 = 5; 

15 * x = 5 + 10;

15 * x = -5 + 10; 

15 * x = 15; 

15 * x = 5; 

x = 1; 

x = 1/3. 

5) 9 * х + 15 = 6; 

9 * x = 6 - 15;

9 * x = -6 - 15;

x = -1;

x = -21/9.

6) 8 * х - 6 = 14; 

8 * x = 14 + 6; 

8 * x = -14 - 6; 

x = 20/8; 

x = -22/8.
