Решите уравнение 3,4х -2х-17 = -11 - 2 3/5х

3,4 * х - 2 * х - 17 = -11 - 2 3/5 * х; 

3.4 * x - 2 * x - 17 = -11 - 2.6 * x; 

x * (3.4 - 2) - 17 = -11 - 2.6 * x; 

x * 1.4 - 17 = -11 - 2.6 * x; 

1.4 * x - 17 = -11 - 2.6 * x; 

1.4 * x + 2.6 * x = -11 + 17; 

x * (1.4 + 2.6) = 17 - 11; 

x * (2 + 2) = 6; 

x * 4 = 6; 

4 * x = 6; 

x = 6/4; 

x = 3/2; 

x = 1.5.
