12.5+10.8n=20.9323+13.079n
Add 4.7 and 7.8 to get 12.5.
12.5+10.8n-13.079n=20.9323
Subtract 13.079n from both sides.
12.5-2.279n=20.9323
Combine 10.8n and -13.079n to get -2.279n.
-2.279n=20.9323-12.5
Subtract 12.5 from both sides.
-2.279n=8.4323
Subtract 12.5 from 20.9323 to get 8.4323.
n=\frac{8.4323}{-2.279}
Divide both sides by -2.279.
n=\frac{84323}{-22790}
Expand \frac{8.4323}{-2.279} by multiplying both numerator and the denominator by 10000.
n=-\frac{37}{10}
Reduce the fraction \frac{84323}{-22790} to lowest terms by extracting and canceling out 2279.
