- From the third equation: `ice cream + ice cream = 2`, so one ice cream cone equals `1`.
- From the second equation: `26 - donut = ice cream`. Since ice cream is `1`, then `26 - donut = 1`, so the donut equals `25`.
- From the first equation: `donut = watermelon + watermelon + popsicle`. Substituting the donut value, `25 = 2 * watermelon + popsicle`.
- From the fourth equation: `watermelon + watermelon = ice cream + 9`. Since ice cream is `1`, this becomes `2 * watermelon = 1 + 9 = 10`, so one watermelon equals `5`.
- Substitute watermelon = `5` into the first equation: `25 = 2 * 5 + popsicle`, so `25 = 10 + popsicle`, meaning the popsicle equals `15`.
- The final question asks for: `watermelon + popsicle + donut`.
- Substituting the values: `5 + 15 + 25 = 45`.
The answer is 45.
