1st interpretation:
1/3x - 1/6x = 9 Multiply all items by 6, thus
6(1/3x) - 6(1/6x) = 6(9)
2x - x = 54
x = 54
Answer: x = 54
Proof:
1/3(54) - 1/6(54) = 9
18 - 9 = 9
9 = 9
2nd interpretation:
1/(3x) - 1/(6x) = 9
2/(6x) - 1/(6x) = 9
1/(6x) = 9
54x = 1
x = 1/54
Answer: x = 1/54
Proof:
(1/[3 * 1/54]) - (1/[6 * 1/54]) = 9
1/(1/18) - 1/(1/9) = 9
18 - 9 = 9
9 = 9
x = 1/18
