Solving
lnx4 + lnx5 = 6 + lnx7

Solving for variable 'l'.

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

Add '-1lnx7' to each side of the equation.
lnx4 + lnx5 + -1lnx7 = 6 + lnx7 + -1lnx7

Combine like terms: lnx7 + -1lnx7 = 0
lnx4 + lnx5 + -1lnx7 = 6 + 0
lnx4 + lnx5 + -1lnx7 = 6

Reorder the terms:
-6 + lnx4 + lnx5 + -1lnx7 = 6 + -6

Combine like terms: 6 + -6 = 0
-6 + lnx4 + lnx5 + -1lnx7 = 0
