-2n=4.85-3.8
Subtract 3.8 from both sides.
-2n=1.05
Subtract 3.8 from 4.85 to get 1.05.
n=\frac{1.05}{-2}
Divide both sides by -2.
n=\frac{105}{-200}
Expand \frac{1.05}{-2} by multiplying both numerator and the denominator by 100.
n=-\frac{21}{40}
Reduce the fraction \frac{105}{-200} to lowest terms by extracting and canceling out 5.
