Answer:
3CuCl2 + 2Ni → 3Cu + 2NiCl3
Steps:
1. since the least common multiple of 8 and 4 is 8, you would have to make both of the denominators 8.
2. 2 times 4 equals 8, 2 times 3 equals 6
3. 35 3/4 now becomes 35 6/8
4. your new problem is 35 6/8 - 1/8
5. 6 -1= 5
6. your answer is 35 5/8
X + 12 = 20
x + 12 -12 = 20 -12
x = 8
