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
21/5
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
12 and 1/2
12/8 or 1 and 1/2
5 over 8 + 7 over 8 = 12 over 8 or 1 1/2
