Answer:

first number=15 second number=6

Step-by-step explanation:

lets take the first and second numbers as "a" and "b"

a-b=9

a+2b=27  (solve these equations simultaneously)

eliminating a

-3b= -18

b= 6

then substitute in the first equation

a-6=9

a=9+6

a=15

I really hope you know how to solve equations simultaneously

hope this helped
