5.36. -6(7 - x) = -8x - 7.
-42 + 6х = -8х - 7
6х+8х = -7 +42
14х = 35
.5.37. 4(-3 + x) = 5x + 2.
-12 + 4х = 5х + 2
-12 - 2 = 5х - 4х
х = - 14
5.38 -5y + 19 = 2(2-6y).
-5y + 19 = 4 - 12y
-5y + 12y = 4 - 19
7y = -15
9 (14 - x) =-2x
9*14 - 9x = -2x
9*14 = -2x+9x
9*14 = 7x
x = 9*14 : 7 = 18
x= 18
4(-3 + x) = 5x + 2
-12+4x = 5x + 2
-12-2 = 5x - 4x
x = -14
-9(1 + 6x) = 6x - 37
-9 -54x = 6x - 37
-9+37 = 6x + 54x
28 = 60x
x = 
-6(7 - x) = -8x – 7
