Solving for x in each equation:

1) 6x + 5x + 4x = 150( x - 8 )
15x = 150x - 1200
15x - 150x = -1200
-135x = -1200
x = -1200 / -135
x = 8.89

2) 8x + x - 4x - 40 = 160
5x - 40 = 160
5x = 200
x = 200 / 5
x = 40

3) 310 + 7x = 380
7x = 70
x = 70 / 7
x = 10

4) 4 x 250 = 1000
1000x = 10000
x = 10000 / 1000
x = 10

5) 90 / x - 32 = 13
90 / x = 45
x = 90 / 45
x = 2

6) ( x - 8 ) * 12 = 132
12x - 96 = 132
12x = 228
x = 228 / 12
x = 19

Therefore, the solutions for each equation are:
1) x = 8.89
2) x = 40
3) x = 10
4) x = 10
5) x = 2
6) x = 19
