Explanation:

Concept:

Whenever in Question said substract this value say 'x' from 'z' then we have to write 'z' first and then substract 'x' from it.e.g=>z-x

$= > c - 4a + b - (7a - 3b + 5c)$

$= > c - 4a + b - 7a + 3b - 5c$

Taking like terms together:-

$= > c - 5c - 4a - 7a + b + 3b$

$= > - 4c - 11a + 4b$

Taking 4 common from both terms:-

$= > 4(- c + b)- 11a$

$= > 4(b - c)- 11a$
