To solve the equation, follow these steps:

- Calculate each term of the equation separately.

- First term: 200. Easy, it's given.

- Second term: 13 × 7 = 91. This is simple multiplication.

- Third term: 30 × 5 = 150. Another multiplication.

- Combine these: 200 + 91 - 150 = 141. This is the left side of the equation.

- Set equal to the right side: ?² - 3.

- Rearrange: ?² = 141 + 3 = 144.

- Conclusively: ? = v144 = 12.

- Correct Option: Option 2: 12

- Answer: 12
