Answer 1

Hence :

$\: \: \: \: \: \: \: \: \: \: \: \: :\implies \sf{ \: \: - \: \: and \: \: - \: becomes \: \: + }$

So :

$\: \: \: \: \: \: \: \:➠ \bold \pink{ - 7x + ( - 10x)}$

$\: \: \: \: \: \: \: \:➠ \bold \pink{ - 7x- 10x}$

here - and - is + so we want to + (add) 7 and 10 then we want to put the symbol of the greatest number which is -7 is operation is - so the answer's operation is also at -

So The answer is :

$\: \: \: \: \: \: \: \:➠ \bold \pink{ - 17x}$

$\sf{\therefore \: option \: c) \red{ - 17x} \: \: \: is \: correct}$
