Question 677779: One number is four times another. Half the sum of the number is 10. What are the two numbers?

x=one number
4x=the other number
x+4x=sum of the two numbers
(x+4x)/2= half the sum of the two numbers
Soooo
(x+4x)/2=10 multiply both sides by 2
5x=20
x=4----one number
4x=4*4=16 the other number
CK
16+4=20
20/2=10
10=10
Hope this helps---ptaylor
