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

Найдем корни.

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.
