Question

From the sum of 5a + 2b – c and 2a – 5b + 2c, take away 3a – 4b + c

Answer 1

$\large \sf{4a + b }$

$\underline \frak{Explanation-}$

Lets first do sum of 5a + 2b – c and 2a – 5b + 2c-

$\: 5a + 2b - c \\ + 2a - 5b + 2c \\ ───────── \\ 7a - 3b + c$

$\boxed{Sum → 7a - 3b + c}$

Now taking Away 3a – 4b + c from sum -

$\: 7a - 3b + c\\ - 3a + 4b - c\\ ───────── \\ 4a+b+0$

$\boxed{Answer → 4a +b}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Note -

Since we are subtracting 3a - 4b + c therefore the signs of terms of expression will change as-

-(3a – 4b + c) = - 3a +4b -c
