- Begin by calculating the sum of the numbers in the numerator: 320 + 342 + 530 + 915 = 2107.

- The division equation is given: 2107 ÷ (60 - x) = 43.

- Solve for x:

- Multiply both sides by (60 - x): 2107 = 43(60 - x).

- Expand: 2107 = 2580 - 43x.

- Rearrange: 43x = 2580 - 2107.

- Calculate: 43x = 473.

- Divide by 43: x = 473 ÷ 43.

- Result: x = 11.

- Options:

- Option 1: 11

- Option 2: 23

- Option 3: 26

- Option 4: 15
