Answer 2

$\Large\red{\mathcal{Question:-}}$

By how much is a+2b-3c greater than 2a-3b+c?

$\Large\green{\mathcal{Solution :-}}$

Term to be subtracted = 2a 3b+c

Changing the sign of each term of the expression gives -2a + 3b - c.

On adding

= (a +2b-3c )+(-2a +3b-c)

= a + 2b - 3c - 2a +3b -c

= (1-2)a + (2+3)b +(-3-1)c

= -a+ 5b - 4c
