Question

The sum of three integers is 126. The second integer is twice as big as the first. Thethird integer is three times the first. Find the three integers.Use x in the equation

Answer 1

we have the following:

`\begin{gathered} 126=x+2x+3x \\ \end{gathered}`

solving:

`\begin{gathered} 126=6x \\ x=(126)/(6) \\ x=21 \end{gathered}`

therefore,

first number is 21

second number is 42 (21*2)

third number is 63 (21*3)
