5. Three times the smallest of three consecutive odd numbers decreased

1.	5. Three times the smallest of three consecutive odd numbers decreased by 7 equals twice the largest one.Find the numbers.
Answer» Consecutive odd numbers (x=smallest): x, x+2, x+4 3x-7 = "three times the smallest … decreased by 7" 2(x+4) = "twice the largest" These two things are equal: 3x-7 = 2(x+4) 3x-7 = 2x+8 x = 15 ---- Ans: the 3 numbers are 15, 17, and 19

5. Three times the smallest of three consecutive odd numbers decreased by 7 equals twice the largest one.Find the numbers.

Answer»

Consecutive odd numbers (x=smallest): x, x+2, x+4

3x-7 = "three times the smallest … decreased by 7"

2(x+4) = "twice the largest"

These two things are equal: 3x-7 = 2(x+4)

3x-7 = 2x+8

x = 15

Ans: the 3 numbers are 15, 17, and 19
