When 8 is subtracted from Ollie's age, the result is the same as subtracting 16 from 3 times his age. How old is Ollie?

Let Ollie's age be L

We subtract 8 from L and subtract 16 from 3 times L as well and equate them.

L - 8 = 3L - 16.

L - 3L = - 16 + 8

-2L = 8 - 16

-2L = - 8 Divide both sides by - 2.

-2L / - 2 = - 8 / - 2

L = 4.

Ollie is 4 years old.
