Answer 2

$\huge\bold{\mathtt{Question⇒}}$

Simplify: $3(a-3b+2c)-(3a-4b-7c)$

$\huge\bold{\mathtt{To\:find⇒}}$

The value of

$3(a-3b+2c)-(3a-4b-7c).$

$\huge\bold{\mathtt{Solution⇒}}$

$3(a-3b+2c)-(3a-4b-7c)$

$= 3a-9b+6c-(3a-4b-7c)$

Remove the bracket.

$= 3a-9b+6c-3a+4b+7c$

$= \cancel{3a}-9b+6c\cancel{-3a}+4b+7c$

$= -9b+6c+4b+7c$

Combine the like terms.

$= (-9b+4b)+(6c+7c)$

$= -5b+13c$

$\huge\bold{\mathtt{Therefore⇒}}$

$3(a-3b+2c)-(3a-4b-7c)$

$= -5b+13c$

$\huge\bold{\mathtt{Final answer⇒}}$

$-5b+13c$
