To simplify the expression, distribute the negative sign through the second set of parentheses and then combine like terms: $3a - 2b - 5c - 9a + 6b + 7c = -6a + 4b + 2c$.

Simplify - (3a−2b−5c)−(9a−6b−7c)( 3 a - 2 b - 5 c ) - ( 9 a - 6 b - 7 c )(3a−2b−5c)−(9a−6b−7c)

Simplify
- $( 3 a - 2 b - 5 c ) - ( 9 a - 6 b - 7 c )$
