The solution of equation 2 (4-x) + 7 = 3x and the solution of equation 3 (x-k) = 4K - (x / 2) about X are reciprocal to each other, and the value of K is obtained

The solution of equation 2 (4-x) + 7 = 3x and the solution of equation 3 (x-k) = 4K - (x / 2) about X are reciprocal to each other, and the value of K is obtained

2(4-x)+7=3x
8-2x+7=3x
5x=15
x=3
Therefore, if the solution of equation 3 (x-k) = 4k-x / 2 is 1 / 3, then x = 1 / 3 is substituted to get the following result:
3*1/3-3k=4k-1/6
7k=1+1/6=7/6
k=1/6

Given that the solution of the equation x-25 = 2-x + 32 is also the solution of the equation | 3x-2 | = B, then B = 0___ ．

2 (X-2) = 20-5 (x + 3), 2X-4 = 20-5x-15, 7x = 9, the solution is: x = 97. Substituting x = 97 into the equation | 3x-2 | = B, the solution is: B = 137
