hi FRIEND
Step-by-step explanation:
let the biggest number be x
and let the smaller number be y.
Then
x-y=8-------------------------------1
x+2=3y------------------------------2
by subsituition method
x=8+y [from 1]------------------3
putting the value of 1 in 2
8+y+2=3y
10=3y-y
10=2y
y=10/2=5
putting the value of y in 3
x=5+4
x=13.
