The sum of three numbers is 142 the second number is for more than two times the first the third number is triple the first number find the largest number

Third number = 69

Step-by-step explanation:

Let x represent the first number

Let 2x+4 represent the second number

Let 3x represent the third number

x + 2x + 4 + 3x = 142

6x + 4 = 142

Subtract 4 from both sides of the equation

6x + 4 - 4 = 142- 4

6x = 138

Divide both sides of equation by 6

x = 23

First number = 23

Second number = 2(23) + 4

                           =50

Third number = 3( 23)

                       = 69

Which means the third number is the largest.
