$(100 \times @ + 30 + 7) + (100 \times 4 + 60 + @) + (100 \times 5 + 10 \times @ + 3) = (1000 \times 1 + 100 \times @ + 10 \times @ + @)$
Simplifying the left side:
$100@ + 37 + 460 + @ + 500 + 10@ + 3 = (100@ + @ + 10@) + (37 + 460 + 500 + 3) = 111@ + 1000$
Simplifying the right side:
$1000 + 100@ + 10@ + @ = 1000 + 111@$
The equation becomes $111@ + 1000 = 111@ + 1000$.
