回答 (11)
✔ 最佳答案
6x - 7 = 0
6x-7+7 = 7
6x - 0 = 7
6x = 7
6x/6 = 7/6
x = 1/1/6
6x - 7 = 0
6x = 7
x = 7/6
Answer: 7/6 or 1 1/6
Proof:
6(7/6) - 7 = 0
7 - 7 = 0
0 = 0
First, add 7 to get it on the right side, so that the "x" is alone.
You'll get 6x=7.
Then, divide the 6x by 6 to get
x=7/6
6x - 7 = 0
6x = 0 + 7
6x = 7
x = 7/6
6x - 7 = 0
6x = 7
x = 7/6 (1 1/6)
