(9 + 7)(9 - 7) = 16 x 2 = 32
(13 + 7)(13 - 7) = 20 x 6= 120
(17 + 9)(17 - 9) = 26 x 8 = 208
(19 + 11)(19 - 11) = 30 x 8 = 240

Given:
9 * 7 = 32
13 * 7 = 120
17 * 9 = 208
To find:
19 * 11 = ?
Analysis:
Let's analyze the given equations to identify the pattern or system used to solve them.
In the first equation, we multiply the first number (9) by the second number (7), and then add 5 to the result. So, 9 * 7 + 5 = 63 + 5 = 68. However, the given answer is 32, which means we subtracted 36 from the calculated result.
Similarly, in the second equation, we multiply 13 by 7, add 5 to the result, and then subtract 3. So, 13 * 7 + 5 - 3 = 91 + 5 - 3 = 93. But the given answer is 120, which means we added 27 to the calculated result.
In the third equation, we multiply 17 by 9, add 5 to the result, and then subtract 7. So, 17 * 9 + 5 - 7 = 153 + 5 - 7 = 151. However, the given answer is 208, which means we added 57 to the calculated result.
Pattern:
From the analysis above, we can observe the following pattern:
- Multiply the first number by the second number.
- Add 5 to the result.
- Subtract a specific number from the calculated result, which is different for each equation.
Solution:
To find the value of 19 * 11, we apply the same pattern:
Step 1: Multiply 19 by 11:
19 * 11 = 209
Step 2: Add 5 to the result:
209 + 5 = 214
Step 3: Subtract a specific number from the calculated result:
214 - 6 = 208
Therefore, 19 * 11 = 208.
Conclusion:
Based on the given system, the correct answer for the unsolved equation 19 * 11 is 208, which corresponds to option 'C'.
