9n-4.5=3.1\left(5n+4\right)
Use the distributive property to multiply 4.5 by 2n-1.
9n-4.5=15.5n+12.4
Use the distributive property to multiply 3.1 by 5n+4.
9n-4.5-15.5n=12.4
Subtract 15.5n from both sides.
-6.5n-4.5=12.4
Combine 9n and -15.5n to get -6.5n.
-6.5n=12.4+4.5
Add 4.5 to both sides.
-6.5n=16.9
Add 12.4 and 4.5 to get 16.9.
n=\frac{16.9}{-6.5}
Divide both sides by -6.5.
n=\frac{169}{-65}
Expand \frac{16.9}{-6.5} by multiplying both numerator and the denominator by 10.
n=-\frac{13}{5}
Reduce the fraction \frac{169}{-65} to lowest terms by extracting and canceling out 13.
