$30-35a$

To gain the answer you need to multiply every item in the brackets by the amount outside the brackets (in this case that is $-5$ ).

#(-5)(7a-6)

$=(-5)7a+(-5)(-6)$

$=-35a+30$

The above is a perfectly acceptable answer but for tidiness, I have rearranged so that it isn't leading with a minus:

$=30-35a$

How do you simplify -5(7a-6)-5(7a-6)?
