Three times the sum of a number and 4 is the same as 18 more than the number what is the number

number x = 3.

Step-by-step explanation:

Given : Three times the sum of a number and 4 is the same as 18 more than the number.

To find : what is the number.

Solution : We have given a statement

According to question :

Let the number= x

Sum of the number and 4 = x + 4

Three times the sum of the number and 4 = 3 ( x +4).

18 more than a number = 18 + x .

Three times the sum of a number and 4 is the same as 18 more than the number.

3 (x+4) = 18 + x

On distributing 3 over ( x+4)

3x + 12 = 18 + x

On subtracting both sides by 12

3x = 18 -12 +x

3x = 6+x

On On subtracting both sides by x

3x -x =6

2x = 6

On dividing both sides by 2

x = 3.

To verify plug x = 3 in 3x + 12 = 18 + x

3(3)+12 =18+3

9+12 = 18+ 3

21 =21

Therefore, number x = 3.
