Question

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?

4(3 + n) = n + 18
3(4 + n) = n + 18
3 n + 4 = n + 18

Answer 1

n = 3

Explanation:

`3(4 + n) = n + 18 \\ 12 + 3n = n + 18 \\ 2n = 6 \\ n = 3`

Answer 2

it is the second choice, because if you read the questions out loud then the second one is the way you would read it.
