15 years

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=(30)/(2)\\i=15`

Ishaan is now 15 years old
