Answer:
12
Step-by-step explanation:
I think you are trying to say [tex]\frac{5}{6} =\frac{10}{x}[/tex].
If that's the case, you can multiply the left side by 2/2:
10/12 = 10/x
Then, since the numerators are the same and the denominator of one side is 12, the denominator of the other side must also be 12. Therefore, x = 12.
I hope this helped.
