Решите примеры, ,выделеные на картинке
1) -A - 2 + 8 - 6A = - 7A + 6
2) 2X + 3X = 5 + 3
5X = 8
X = 85 = 1.6
3) - 14 + 12X = - 3 + 10X
2X = 11
X = 5.5
4) 2.9Y - 4.8 + 4Y = 5.4Y + 10.8
6.9Y- 5.4Y = 10.8 + 4.8
1.5Y = 15.6
Y = 10.4
5) 34X - 34 + 2X = 32 + X
34X + 2X - X = 32 + 34
74X = 94
7X = 9
X = 97 = 1 27
