Answer:

15 years

Step-by-step explanation:

Complete Question:

Ben is 4 times as old as Ishaan. 6 years ago, Ben was 6 times as old as Ishaan. How old is Ishaan now?

Let Ben's age be "b" and Ishaan's age be "i"

Since Ben is 4 times as Ishaan, we can write:

b  = 4i

Ben was 6 times as Ishaan, BUT 6 years ago, we setup the equation like shown below:

b - 6 = 6(i - 6)

Multiplying, we have:

$b - 6 = 6(i - 6)\\b-6=6i-36$

Now, we replace b with "4i" and solve for i (Ishaan's age now):

$b-6=6i-36\\4i-6=6i-36\\2i=30\\i=\frac{30}{2}\\i=15$

Ishaan is now 15 years old
