Solution for lnx+ln(x+4)=ln(77) equation: 


Simplifying
lnx + ln(x + 4) = ln(77)

Reorder the terms:
lnx + ln(4 + x) = ln(77)
lnx + (4 * ln + x * ln) = ln(77)
lnx + (4ln + lnx) = ln(77)

Reorder the terms:
4ln + lnx + lnx = ln(77)

Combine like terms: lnx + lnx = 2lnx
4ln + 2lnx = ln(77)

Reorder the terms for easier multiplication:
4ln + 2lnx = 77ln

Solving
4ln + 2lnx = 77ln

Solving for variable 'l'.

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

Add '-77ln' to each side of the equation.
4ln + -77ln + 2lnx = 77ln + -77ln

Combine like terms: 4ln + -77ln = -73ln
-73ln + 2lnx = 77ln + -77ln

Combine like terms: 77ln + -77ln = 0
-73ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-73 + 2x) = 0
