Step-by-step explanation:

a-7b-3c

-4a +3b +8c

=-3a-4b+5c

Step-by-step explanation:

Subtract ( a - 7b - 3c ) from (-4a + 3b + 8c)

[tex] \longrightarrow \: (a - 7b - 3c) - ( - 4a + 3b + 8c)[/tex]

[tex] \longrightarrow \: a - 7b - 3c + 4a - 3b - 8c[/tex]

[tex] \longrightarrow \: 5a - 10b - 11c[/tex]
