    -10-(10n+8)=-78 and by switching the signs of everything -[-10-(10n+8)]=-78

    okay but what happens with the negative in front of the absolute value?

    I mean switching the signs of the side with variable in it.

    \[\large\rm -10-|10n+8|=-78\]Should probably add 10 to each side before dealing with the signs that the absolute value gives us :)\[\large\rm -|10n+8|=-68\]

    You make it into parentheses, so just ignore the absolute value Negative times negative makes it positive

    the -68 involves a fraction.
