Question

The difference between two numbers is 9.

The first number plus twice the other numbe
is 27. Find the two numbers.

Answer 1

first number=15 second number=6

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
