Question

Ben is 39 years old and Ishaan is 3 years old. How many years will it take until Ben is only 4 times as old as Ishaan?

Answer 1

Answer:

$9\ years$

Step-by-step explanation:

Let

x------> the number of years

we know that

$(39+x)=4(3+x)$

Solve for x

$39+x=12+4x$

$4x-x=39-12$

$3x=27$

$x=9\ years$
