-15ln + lnx + 0 + nxL = 0 + -2nL
-15ln + lnx + nxL = 0 + -2nL
Remove the zero:
-15ln + lnx + nxL = -2nL

Add '-1nxL' to each side of the equation.
-15ln + lnx + nxL + -1nxL = -2nL + -1nxL

Combine like terms: nxL + -1nxL = 0
-15ln + lnx + 0 = -2nL + -1nxL
-15ln + lnx = -2nL + -1nxL

Reorder the terms:
-15ln + lnx + 2nL + nxL = -2nL + 2nL + -1nxL + nxL

Combine like terms: -2nL + 2nL = 0
-15ln + lnx + 2nL + nxL = 0 + -1nxL + nxL
-15ln + lnx + 2nL + nxL = -1nxL + nxL

Combine like terms: -1nxL + nxL = 0
-15ln + lnx + 2nL + nxL = 0
