We need to compute (17*23) + (144/12) - 89.
Compute step by step:
17 * 23 = ?
17*20=340, plus 17*3=51 => total 391.
144 / 12 = 12.
Now (17*23)+(144/12)-89 = 391 + 12 - 89 = 403 - 89? Wait 391+12=403. Then 4
403-89 = 314.
Answer X = 314.
...done thinking.
**Step‑by‑step calculation**
1. Compute the multiplication:
\(17 \times 23 = 391\)
2. Compute the division:
\(\frac{144}{12} = 12\)
3. Combine them as given:
\((17\times23) + (144/12) - 89 = 391 + 12 - 89\)
4. Add the first two terms: \(391 + 12 = 403\)
5. Subtract the last term: \(403 - 89 = 314\)
**Answer:** X = **314**.
