Question

решите уравнение 3×(2 3/5 -х) + 3 1/5=4 1/3 ​

Answer 1

Пошаговое объяснение:

3 * (2 3/5 - х) + 3 1/5 = 4 1/3

3 * (2 3/5 - х) = 4 1/3 - 3 1/5

3 * (2 3/5 - х) = 4 5/15 - 3 3/15

3 * (2 3/5 - х) = 1 2/15

2 3/5 - х = 1 2/15 : 3

2 3/5 - х = 17/15 * 1/3

2 3/5 - х = 17/45

х = 2 3/5 - 17/45

х = 2 27/45 - 17/45

х = 2 10/45

х = 2 2/9
