Question

Which could be used to find the number n? “Four less than a number, n, is equal to fifteen.”

A, ,B C, Or D

Answer 1

C (n - 15 = 4)

Explanation:

This is the answer becuase it can be rewritten as:

n - 4 = 15 (by subtracting 4 from both sides and adding 15 to both sides);

this equation describes the "written" (verbal) equation.
