Помогите пожалуйста до завтра
11(x-1) = 3*(x+2)
11x - 11 = 3x + 6
11x - 3x = 6 + 11
8x = 17
x = 17 : 8
x = 2,125
-------------------
7x - 2x = 49
5x = 49
x = 49 : 5
x = 9,8
----------------------
44x + 10 = 40*(x + 2)
44x + 10 = 40x + 80
44x - 40x = 80 - 10
4x = 70
x = 70 : 4
x = 17,5
--------------------
6x + 3*(x + 1) = 7x + 17
6x + 3x + 3 = 7x + 17
9x + 3 = 7x + 17
9x - 7x = 17 - 3
2x = 14
x = 14 : 2
x = 7
------------------
9x + 22 = 4*(2x + 5)
9x + 22 = 8x + 20
9x - 8x = 20 - 22
x = -2
