Two Numbers with a Sum of 5 and a Difference of 3

Define variables:
Let x = larger number and y = smaller number
Resulting system of equations:
x + y = Sum
x − y = Difference
Solve the system of equations for x (larger number):
x =  
Sum + Difference/2

Find x by substituting given Sum and Difference into equation for x and simplify:
x =  
5 + 3/2

x =  
8/2

x =  4
Solve the system of equations for y (smaller number):
y =  
Sum − Difference/2

Find y by substituting given Sum and Difference into equation for y and simplify:
y =  
5 − 3/2

y =  
2/2

y =  1
Therefore, the two Numbers are 4 and 1
