Answer:
22, -6
Explanation:
Create a system of equations.
x= the larger number
y=the smaller number
Using what you know, create the equations:
x+y=16
3x-y=72
Now add the two equations together. (elimination method)
x+y=16
+ 3x-y=72 (the y's cancel out)
-----------------
4x = 88 Divide.
x = 22
Now plug in x=22 into one of your equations to solve for y.
x+y=16
22+y=16
y=-6
The numbers are 22 and -6.
