To solve this verbal equation, first we need to convert it into an written equation using integers and variables.

3n=2n-7

N is the variable for "the number".

We are trying to get the variable on one side of the equation to solve it.

So, we need to subtract 2n from both sides, which results in the equation

n = - 7

"The number" is - 7.
