Three multiplied by the sum of 4 and a number is the same as 18 more than the number. find the number.

if n is " the number," which equation could be used to solve for the number?

3n+4=n+18

4 (3+n)=n+18

3 (4+n)=n+18

3 (4+n)=n+18

Step-by-step explanation:

Let the unknown number be n.

Then 3(4 + n) = n + 18.  This matches the third answer choice.

C.

Step-by-step explanation:

Let n represent the number.

The sum of 4 and a number would be .

Three multiplied by the sum of 4 and a number would be .

18 more than the number would be .

To solve for the number, we will equate both expression as:

Therefore, our required equation would be .

Let us solve for n.

Therefore, the number is 3.
