Question

The sum of three numbers is 30. The third number is twice the second, and is also 2 less than 3 times the first. What are the three numbers?

Answer 1

First: 6 Second: 8 Third:16

Explanation:

First number:x

Second number: 1.5x-1

Third number: 3x-2

x+1.5x-1+3x-2=30

5.5x-3=30

5.5x=33

x=33/5.5=6

So First =6

Second= 1.5(6)-1=8

Third " 3(6)-2=16
