Пошаговое объяснение:
9(7-6x)=-8(2+4x)-2(2x+1)-9x
63 - 54x = -16 - 32x - 4x - 2 - 9x
63 - 54x = -45x - 18
54x - 45x = 63 + 18
9x = 81
x = 81 : 9
x = 9
6(3-x)=-(18+6x)
18 - 6x = -18 - 6x
6x - 6x = -18 - 18
0 ≠ -36 (нет корней)
6(2x+9)-32x=-4(5x-4)+38
12x + 54 - 32 = -20x + 16 + 38
12x + 22 = -20x + 54
12x + 20x = 54 - 22
32x = 32
x = 32 : 32
x = 1
-4x+9(8x-9-4x)=-6-5(2-5x+6)
-4x + 72x - 81 - 36x = -6 - 10 + 25x - 30
32x - 81 = 25x - 46
32x - 25x = 81 - 46
7x = 35
x = 35 : 7
x = 5
