Question

The sum of three consecutive odd integers is 21 less than 4 times the largest number. Find the 3 numbers.

Answer 1

11, 13, 15

Explanation:

Let x be the smallest odd number

x + (x + 2) + (x + 4) = 4(x + 4) - 21

3x + 6 = 4x + 16 - 21

3x + 6 = 4x - 5

x = 11

Numbers are: 11, 13, 15

Answer 2

11,13,15

Explanation:

x+(x+2)+(x+4)=4(x+4)-21

3x+6=4x-5

11=x

x=11

x+2=13

x+4=15
