THE DIFFERENCE BETWEEN TWO NUMBERS IS 16. FIVE TIMES THE SMALLER IS THE SAME AS 8 LESS THAN THREE TIMES THE LARGER. FIND THE NUMBERS? HOW DO YOU SOLVE THIS? PLEASE.

two numbers: x,y
xy=16
5y=83x
u have to solve this system 
HOW DO YOU SOLVE 5Y=83X? (BIG HELP)

L1: xy=16
L2: 5y=83x
in L1: x=16+y
so in L2 : 5y=83*(16+y)=8483y
so 8y=40
y=5
in L1 : xy=16
x(5)=16
x=11
if u don't understand this, u have to read your math lesson
