Решите уровненное |2x|=6 |3x|=12 |5x|+3=8 |4x|+5=1 |1,5x|2=4 7-|6x|=-5

Решим уравнение.

1) |2 * x| = 6;

{ 2 * x = 6;

2 * x = - 6;

{ x = 6/2;

x = - 6/2;

{ x = 3;

x = - 3;

2) |3 * x| = 12;

{ 3 * x = 12;

3 * x = - 12;

{ x = 12/3;

x = - 12/3;

{ x = 4;

x = - 4;

3) |5 * x| + 3 = 8;

|5 * x| = 8 - 3;

|5 * x| = 5;

{ x = 5/5;

x = - 5/5;

{ x = 1;

x = - 1;

4) |4 * x| + 5 = 1;

|4 * x| = 1 - 5;

|4 * x| = - 4;

Нет корней.

5) |1,5 * x| * 2 = 4;

|1,5 * x| = 4/2;

|1,5 * x| = 2;

{ 1.5 * x = 2;

1.5 * x = - 2;

{ 3 * x = 4;

3 * x = - 4;

{ x = 4/3;

x = - 4/3;

6) 7 - |6 * x| = - 5;

-|6 * x| = - 5 - 7;

-|6 * x| = - 12;

|6 * x| = 12;

{ x = 12/6;

x = - 12/6;

{ x = 2;

x = - 2.
