How do I solve this equation for N, b/c I completely forgot how to do
it:

N/(7500-N)=.0204082e^.8472969T

Rational expressions where the variable appears on both the numerator
and denominator were always hard for me. Thanks!!!!


STEP 1: Clear denominators by cross-multiplying.

STEP 2: Move all terms that involve N to the left side, all others to
the right.

STEP 3: Factor out N from all terms on the left (in this example, all
you get are terms in N).

STEP 4: Divide through to isolate N.
