Answer:

24 and 6 are the 2 numbers

Step-by-step explanation:

let the 2 numbers be x and y , then

x + y = 30 → (1)

y = 4x → (2) [ one number is 4 times the other ]

Substitute y = 4x into (1)

x + 4x = 30

5x = 30 ( divide both sides by 5 )

x = 6

Substitute x = 6 into (2)

y = 4 × 6 = 24

The 2 numbers are 24 and 6
