here giving 100 for right answer

Answer:
6
Step-by-step explanation:
x-3 6
---- = ----
5 10
to get from 5 to 10 we multiply 5 by 2
so...
to find out what x is we need to divide 6 by 2
which is
= 3
so we know that x-3 has to be equal to 3
therefore x=6
and to check:
6-3= 3
so
3 6
-- = ----
5 10
therefore x=6
