Решите уровнениех+2.7=3 3 2х-5=х1 4 +х=1 х-0.6=1.4 х-1 1=4 2.7х+1.3=х+3 5

Вычислим корешки.

1) х + 2.7 = 3;

x = 3 - 2.7;

x = 0.3;

Ответ: х = 0,3.

2) 2 * х - 5 = х; 

2 * x - x = 5; 

x * (2 - 1) = 5;

x * 1 = 5;

x = 5.

3) 4 + х = 1; 

x = 1 - 4;

x = -3.

4) х - 0.6 = 1.4; 

x = 1.4 + 0.6;

x = 2.

5) х - 1 = 4; 

x = 4 + 1; 

x = 5.

6) 2.7 * х + 1.3 = х + 3; 

2.7 * x - x = 3 - 1.3; 

1.7 * x = 2 - 0.3; 

1.7 * x = 1.7; 

x = 1.7/1.7; 

x = 1.
