Two Numbers with a Sum of 35 and a Difference of 13

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 =  
35 + 13/2

x =  
48/2

x =  24
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 =  
35 − 13/2

y =  
22/2

y =  11
Therefore, the two Numbers are 24 and 11
Check Sum of the two Numbers:
