Respuesta :
Sam is 10 years old because 20 is half of 40 and 20 subtract 10 is 10
The age of Sam will be 10 if his aunt's age is 40.
How to solve linear equation?
According to question,
Age of aunt is 40.
Half of the age of aunt is equal to 20.
10 years younger than half of auntys age means(20-10)=10
So, equation can be written as:-
(X÷2)-10= age of Sam
∴(40÷2)-10=10 years.
