When it says, "Paulo has a certain amount of money. If he spends six dollars, then he has 1/4 of the original amount left."

So would the equation be n-6=1/4?

n - 6 = (1/4)n
Okay, but I was stuck when trying to find the answer.
My process was:
n-6=(1/4)n
n=(6^1/4)n
at this step I am stuck to know what to do next. Please help.
n - 6 = (1/4)n

Subtract (1/4)n from both sides,
Add 6 to both sides.

(3/4)n = 6

n = 6 / (3/4)

n = 6 * (4/3)

n = 24/3 = 8
Wait. How could you add 6 on both sides if the (1/4)n has been subtracted on both sides?
