Answer:

FIRST NUMBER IS 10 AND SECOND NUMBER IS 40

Step-by-step explanation:

LET THE SECOND NUMBER BE Y AND FIRST BE X

Y = 4X …….1

X + Y = 50…… 2

WE SOLVE SIMULTANOUSLY  

PUTTING Y = 4X IN EQUATON 2

X + 4X = 50

5X = 50

DIVIDING EACH TERM BY 5

5X/5 = 50/5

X = 10

THEN PUTTING X = 10 IN EQUATION  1

Y = 4(10)

Y = 40
