Jackson collected 24 seashells, while Petra and Tyron each collected 35.
You can illustrate Petra/Tyron's number of seashells as x = 2s - 13.
Therefore, the problem can be set up like this:
2(2s-13) + s = 94, with s being the number of Jackson's shells.
That simplifies to 5s - 26 = 94, which means s = 24. Therefore, Jackson collected 24 seashells.
Then simply plug 24 in for s and apply it to the equation for finding x, which would be 2(24) - 13. That ends up being 35.
Therefore, Petra and Tyron both collected 35 seashells!
