James is four time as old as peter if their combined age is 30 how old is James.

Let j be Jame's age. Let p be Peter's age. We're given:

1. j = 4p
2. j + p = 30

Substitute (1) into (2)
4p + p = 30

Combine like terms:
5p = 30

Type 5p = 30 into our search engine, and we get p = 6.

Plug p = 6 into equation (1) to get James's age, we get:
j = 4(6)
j = 24
