Question

three times the smallest of three consecutive odd numbers decreased by 7 equal twice the largest one. find the numbers

Answer 1

Let the smallest number be x

other two are x+2 and x+4

by the condition given in your question we get the equation

3 (x)-7=2 (x+4)

3x-7=2x+8

x=15

so the numbers are 15,17&19

Answer 2

let the numbers be X,X+2,X+4
Smallest no. is x
3x- 7 = 2* (X+4)
3x- 7 = 2x+8
X=15
the numbers are 15,17,19
