Lois is four times as old as her son Don. The sum of their ages is 40. How old is Don? a.Create an equation that can be used to solve this problem.

Answer 1

Explanation:

If Lois is 4 times as old as her son and we don't know how old the son is, the son's age is x and his mother's age is 4x (4 times the son's age). The word sum means to add, so the equation for this is

x + 4x = 40
