Question

which equation represents this sentence? three less than the product of seven and a number is four more than the number. 3 - 7n + 4 = n 7n - 3 = n + 4 3 - 7n = n + 4 7n - 3 + 4 = n

Explanation:

Step1: Define the number

Let the number be $n$.

Step2: Translate "the product of seven and a number"

The product of seven and a number is $7n$.

Step3: Translate "Three less than the product of seven and a number"

Three less than $7n$ is $7n - 3$.

Step4: Translate "four more than the number"

Four more than the number $n$ is $n + 4$.

Step5: Set up the equation

Since "Three less than the product of seven and a number is four more than the number", the equation is $7n-3=n + 4$.

Answer:

$7n - 3=n + 4$ (the second option)
