40n=-8

jimthompson5910 (jim_thompson5910):

40n means 40 times n you want to isolate 'n' so you have to undo the multiplication by 40, which means you must divide both sides by 40

OpenStudy (selena2345):

How

jimthompson5910 (jim_thompson5910):

40n/40 = 1n or just n so on the left side, 40n turns into just 'n'

jimthompson5910 (jim_thompson5910):

you must do the same to both sides, so divide -8 by 40 and reduce

jimthompson5910 (jim_thompson5910):

n = ???

Can You Show Me Jim how to solve it

jimthompson5910 (jim_thompson5910):

-8/40, what does that reduce to?

OpenStudy (selena2345):

-1/5

jimthompson5910 (jim_thompson5910):

good, so n = -1/5

OpenStudy (selena2345):

Can You Show me how you will solve it

jimthompson5910 (jim_thompson5910):

40n = -8 40n/40 = -8/40 1n = -8/40 n = -1/5 This is basically what we did, just all in one place
