Question

7/5N + 3/5= -N HOW TO WORK

Answer 1

multiply by 5, subtract by 3, add by 5N, combine like terms, and divide off the 12 perhaps

Answer 2

\[\frac{7}{5}N+\frac{3}{5}=-N\]
\[\frac{7(5)}{5}N+\frac{3(5)}{5}=-(5)N\]
\[7N+3-3=-5N-3\]
\[7N+5N=-3\]
\[12N=-3\]
\[\frac{12N}{12}=\frac{-3}{12}\]
\[N=-\frac{3}{12}=-\frac{1}{4}\]

Answer 3

algebra is alot like shuffling cards

Answer 4

why didnt the 3(5) make it 15?

Answer 5

becasue 5/5 = 1 in the end of it. but dont let that confuse you; we could have gone thru that step just as well.

\[\frac{3(5)}{5}=\frac{15}{5}=3\]

Answer 6

ok i am still skipping steps

Answer 7

just take practice :)
