Question

Which equation would you use to solve the problem," Four less than the product of 3 and a number is 15"

A) 3n - 4 = — 15
B) 3 (n - 4) = — 15
C) 4 - 3n = — 15
D) 4(3n - 4) = 15​

Answer 1

The correct option is a) 3n - 4 = 15

Explanation:

The product of 3 and a number means 3 multiplied by a number (n)

So it'll be 3*n or simply 3n

Now, it says 4 less than the product

So 4 less than 3n

That is equal to 3n minus 4 or 3n -4

So we come to the conclusion that

3n - 4 = 15

Hope this helps!

Answer 2

The answer is a. 3n - 4 = 15
