The combination of Wendell and Maggie’s ages is 33. Wendell’s age is 3 less than 3 times the age of Maggie. How old is Wendell?

AnnyKZ [126]

Step-by-step explanation:

The combination of Wendell and Maggie’s ages is 33. Let Maggie's age is x. It is mentioned that Wendell’s age is 3 less than 3 times the age of Maggie. It means, Wendell’s age is (3x-3).

ATQ,

$x+(3x-3)=33\\\\4x-3=33\\\\4x=36\\\\x=9$

The age of Maggie is x. So, Wendell's age is :

$y=(3x-3)\\\\y=(3(9)-3)\\\\y=24$

So, Wendell age is 24 years.
