the answer is -1
x - 8 + x - 5 + x + 1 = 3x - 12
1 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 12 + 133 + 4 = 195
5 + 8 + 20 + 12 + 19 = 64
12/8 or 1 and 1/2
5/12 plus 1/8 = 13/24
the answer is -1
x - 8 + x - 5 + x + 1 = 3x - 12
81/4+ 15/12= 8 + 1 + 1/4 + 5/12 = 9 + 3/12 + 5/12 = 9 + 8/12 = 92/3
12 - 8 + 3 + 5 = 12
1 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 12 + 133 + 4 = 195
In modular arithmetic, specifically modulo 12, 8 plus 5 equals 1. In this system, numbers "wrap around" after reaching 12, so 8 plus 5 is 13, but when divided by 12, the remainder is 1. This concept is commonly used in clock arithmetic and music theory to represent repeating patterns.

5 + 8 + 20 + 12 + 19 = 64
the answer is 24. what you can do is: 5+3=8 8+4=12 12+3=15 15+10=25 25-1=24
