The number of stickers John and Ken have in the end is 6 and 18 respectively.
<h3>How to write and solve equation?</h3>
let
- Ken stickers = x
- John stickers =3x
New stickers
x + x - 12 = 3x + 5x
2x - 12 = 8x
-12 = 8x - 6x
-12 = -2x
x = 12/2
x = 6
So,
Ken stickers = x
= 6 stickers
John stickers = 3x
= 3 × 6
= 12 stickers
