124 задание спасибоо для вас

1) 11x + 8x = 456

19x = 456

x = 24

2) 38x - 14x = 1608

24x = 1608

x = 67

3) y + 27y = 1204

28y = 1204

y = 43

4)14x - x - 28 = 167

13x = 167 + 28

13x = 195

x = 15

5)8a + 7a + 15 = 420

15a = 420-15

15a = 405

a = 27

6) 16y - 7y + 38 = 3683

9y = 3645

y = 405

Уравнения совершенно простые
1) 19x = 456; x = 456/19 = 24
2) 24x = 1608; x = 1608/24 = 67
3) 28y = 1204; y = 1204/28 = 43
4) 13x = 195; x = 195/13 = 15
5) 15a = 405; a = 405/15 = 27
6) 9y = 3645; y = 3645/9 = 405
Подсчитано в разуме!
