Kellie's original number given the analogy and corresponding equation is 13

How to write and solve equation?

let

  • the unknown number = x

(x × 2) × 3 = x + 65

2x × 3 = 65 + x

6x = 65 + x

6x - x = 65

5x = 65

  • divide both sides by 5

x = 65/5

x = 13

check:

6x = 65 + x

6(13) = 65 + 13

78 = 78

Therefore, the unknown number, x is 13
