Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '5.4n' to each side of the equation.
6.6 + -17.4n + 5.4n = 17.4 + -5.4n + 5.4n

Combine like terms: -17.4n + 5.4n = -12n
6.6 + -12n = 17.4 + -5.4n + 5.4n

Combine like terms: -5.4n + 5.4n = 0.0
6.6 + -12n = 17.4 + 0.0
6.6 + -12n = 17.4

Add '-6.6' to each side of the equation.
6.6 + -6.6 + -12n = 17.4 + -6.6

Combine like terms: 6.6 + -6.6 = 0.0
0.0 + -12n = 17.4 + -6.6
-12n = 17.4 + -6.6

Combine like terms: 17.4 + -6.6 = 10.8
-12n = 10.8

Divide each side by '-12'.
n = -0.9

Simplifying
n = -0.9
