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) + 18 > n

3(n+4)=n+18

The value of n is 3

Step-by-step explanation:

Let n be the required number.

Sum of 4 and the number n is (n +4)

Three multiplied by the sum of 4 and the number= 3(n +4)

Now, 18 more than the number = (n + 18)

From, the given directions, we can write the equation

Now, we solve this equation for n

Distribute 3 over the parenthesis

Subtract n to both sides

Subtract 12 to both sides

Divide both sides by 2

Therefore, the required equation is

3(n+4)=n+18

The value of n is 3
