Answer 2

Answer:

21 and 3

Step-by-step explanation:

Let the numbers be x and y

Therefore according to 1st condition

x = 7y ---------(1)

According to 2nd condition

x-y = 18 ------------(2)

Substituting value of (1) in (2)

7y-y = 18

6y = 18

y = 18/6

y = 3 ----------(3)

x = 7(3) -------------From (1) and (3)

x = 21
