Starting with the first equation:

10(1.37k - 0.12k) / 5 / 8 = 0
0.12k 10/5/8 = 0
0.12k * 2 = 0
0.24k = 0
k = 0

Moving to the second equation:

(0.87m - 0.66m) 10 / 2 / 3 = 0
0.21m 10 / 2 / 3 = 0
2.1m / 6 = 0
0.35m = 0
m = 0

Now, for the third equation:

(15b + b) / 4 = 3
16b / 4 = 3
4b = 3
b = 0.75

Then the fourth equation:

(7a - 2a) 8 = 80
5a 8 = 80
40a = 80
a = 2

Next, the fifth equation:

14y - 2y + 76 = 100
12y + 76 = 100
12y = 24
y = 2

Lastly, we'll solve the sixth equation:

22x + x - 10 = 59
23x - 10 = 59
23x = 69
x = 3

So, the solutions are:
k = 0
m = 0
b = 0.75
a = 2
y = 2
x = 3
