The sum of three numbers is 106. The third number is two times the first number plus two. The second number is three times the first number. What is the first number

Respuesta :

The sum of three numbers is 106. The third number is two times the first number plus two. The second number is three times the first number. The first number is 17 and this question can easily be solved using linear equation in one variable.

Solution: Let the first number be x

then the second number = 3x

also, the third number = 2 (x + 2)

now according to question

x + 3x + 2 (x + 2) = 106

4x + 2x + 4 = 106

6x = 106 - 4

6x = 102

x = 17

hence the first number is 17.
