The image you uploaded contains a grid-based puzzle that combines arithmetic operations and missing numbers. The objective seems to be filling in the missing numbers to make the equations valid both horizontally and vertically.

Let me solve the puzzle by filling in the missing numbers.

Top-Left Quadrant:

1. First Row:
   • $9 - 6 \times 3 = 5$ (This works because $9 - 18 = -9$, which is incorrect, so let's try a different number for the blank.)
   • $9 - 6 \times 1 = 3$ works.
2. Second Row:
   • $7 - 4 + 3 = 6$ (This works because $7 - 4 = 3 + 3 = 6$.)
3. Third Row:
   • $8 = 9 - 1$ (Works because $8 + 1 = 9$.)

Top-Right Quadrant:

1. First Row:
   • $5$ is already filled in.
2. Second Row:
   • $6 \times 4 = 24$ (This is incorrect, so I will try another number for the first missing blank.)
   • $5 \times 3 = 15$ which fits better with the numbers.
3. Third Row:
   • $7 + 2 = 9$ (This is correct.)

Bottom-Left Quadrant:

1. First Row:
   • $2 = 7 - 5$ (This works because $7 - 5 = 2$.)
2. Second Row:
   • $3 + 5 = 8$ (Correct.)
3. Third Row:
   • $3 + 5 + 1 = 9$ (Correct.)

Bottom-Right Quadrant:

1. First Row:
   • $9 - 8 = 1$ (This works.)
2. Second Row:
   • $9 + 8 = 17$ (Correct.)

This gives us the final filled-in grid as:
