6/10 - 9/x = ?
9/x (simplify)
6/10 - 9/x = ?
3/5 (simplify this as well)
3/5 - 9/x=?
L (denominator) : 5
R (denominator) : x
LCM (Least common multiple) : 5 (x)
Switch the denominators around
L (denominator) : x
R (denominator) : 5
3 (x) - 45 / 5 (x)
3 (x) ➡3 (x - 15)
3 (x) - 15 / 5 (x) = ?
3 (x) - 15 = ?
3 = ? (lets solve this problem)
x - 15 = ?
Now, lets add (+) the number 15 from each of the side sides of the problem that is shown above. (x - 15 = ?)
Finally, we get our result of this problem
x = 15

The answer is B 15 ...
First flip both side: 10/6 = x/9
Find for x:
(10/6) = * / 9
(10/6) * 9 = x
x = 15
