Let ,two numbers are x and y
By first condition
x+y =60. ............(1)
by second condition
x=4y
x-4y= 0 ............(2)
now, Subtract eqn 2 from 1
x + y = 60
-
(-) x -(+) 4y = 0
_______________
5 y =60
y = 60/5
y = 12
put y = 12 in eqation (1)
x+ y= 60
x+ 12=60
x= 60-12
x= 48
Therefore ( x, y ) = ( 48 , 12 )
