Question

3 times the smallest of 3 consecutive odd number decreased by 7 equals twice the largest number .find the number​

Answer 1

let the three consecutive odd numbers be 2x+1, 2x+3 and 2x+5.

Equation

3(2x+1) - 7 = 2(2x+5)

6x + 3 - 7 = 4x + 10

6x - 4x = 10 + 4

2x = 14

x = 7

The 3 consecutive odd numbers are 15, 17 and 19
