Solution for ln(x+4)-ln(4)=ln(18) equation: 


Simplifying
ln(x + 4) + -1ln(4) = ln(18)

Reorder the terms:
ln(4 + x) + -1ln(4) = ln(18)
(4 * ln + x * ln) + -1ln(4) = ln(18)
(4ln + lnx) + -1ln(4) = ln(18)

Reorder the terms for easier multiplication:
4ln + lnx + -1 * 4ln = ln(18)

Multiply -1 * 4
4ln + lnx + -4ln = ln(18)

Reorder the terms:
4ln + -4ln + lnx = ln(18)

Combine like terms: 4ln + -4ln = 0
0 + lnx = ln(18)
lnx = ln(18)
