-10n+50=-7(4n+8)-2 no solution many solution
ziro4ka [17]

Answer:

n=-6

Step-by-step explanation:

distribute -7 into (4n+8)

-10n+50=-28n-56-2

combine like terms

-10n+50=-28n-58

add -28n on both sides

-10n+28n+50=-58

combine like terms again

18n+50=-58

subtract 50 on both sides

18n=-108

divide both sides by 18

\frac{18x}{18} =\frac{-108}{18}

x=-6

hope this helps

What the answer of a/7 = -15
IceJOKER [234]
The answer would be -105. If you multiply 7 x -15 it would give you -105 and then you would have to divide -105 by 7 and its equal to -15.
