Question

Pauli noticed that if he began with his age, add 24, divide the result by 2, and then subtract 6, he got his age back. What is Pauli's age?

Answer 1

Let his age be x

Begins with his age, so we set up

x = __________

Add 24, divide the result by 2, then subtract 6

You have to be careful with brackets on this one

(x + 24)/2 - 6

“Got his age back” means the above expression ends up equaling x again

See if you can solve for x based on that
