$a)~~-2a \\ b)~~2xy \\ c)~~-6ac \\ d)~~-3am \\ e)~~a^2 \\ f)~~6xy^2 \\ \\ g)~~ \frac{10bc-bc}{5} = \frac{9bc}{5} \\ \\ h)~~ \frac{5x^2-4x^4}{10} = \frac{x^2}{10} \\ \\ i)~~ \frac{3mn-8mn}{4} =- \frac{5mn}{4} \\ \\ j)~~14x-10x=4x$

$k)~~-7y^2+3y^2=-4y^2 \\ \\ l)~~12ab-11ab=ab \\ \\ m)~~12a^2m-12a^2m=0 \\ \\ n)~~-3xy+7xy=4xy \\ \\ o)~~-17n^3+20n^3=3n^3 \\ \\ p)~~-8am+9am=am$

$q)~~ \frac{6a^4+4a^4-9a^4}{6} = \frac{a^4}{6} \\ \\ r)~~ \frac{5bc-8bc-bc}{10} =- \frac{4bc}{10} \\ \\ s)~~ \frac{-x+3x-x}{10} = \frac{x}{10}$
