Question

John is 8 years younger than Ahmad. If the sum of their ages is 38, how old is John?

Answer 1

Let x equal Ahmad’s age.
Since John is 8 years younger than Ahmad, the equation would be as follows:

x+x-8=38

Solve for x:

2x-8=38
38+8=46
2x=46
x=23

23 is Ahmad’s age, subtract 8 from this and you’ll get 15 for John’s age.
