Answer 4

do you mean \[l=\frac{ nr }{ R}+nr\] ?

Answer 5

no

Answer 6

gotcha!

Answer 7

\[I=\frac{ nr }{ nr+R }\]
so your goal is to isolate the "R", and you would do so by doing the opposite of everything in the equation (EXCEPT FOR R) in order to move everything else to the other side of the equation

Answer 8

would it be no solution

Answer 9

no it would not be, let's start off by moving one of the "nr"s to the other side of the equation, and we do that by doing the opposite of division since it's in a fraction, so what would you do to both sides of the equation?

Answer 10

u would mutlply it by the lcd. or would u factor

Answer 11

mutlpy both side by nr+r

Answer 12

i think

Answer 13

you do not have to do either! both sides of the equation have nothing in common, so there is no lcd
