Solution for ln(x+2)=7+ln(x-1) equation:


Simplifying
ln(x + 2) = 7 + ln(x + -1)

Reorder the terms:
ln(2 + x) = 7 + ln(x + -1)
(2 * ln + x * ln) = 7 + ln(x + -1)
(2ln + lnx) = 7 + ln(x + -1)

Reorder the terms:
2ln + lnx = 7 + ln(-1 + x)
2ln + lnx = 7 + (-1 * ln + x * ln)
2ln + lnx = 7 + (-1ln + lnx)

Add '-1lnx' to each side of the equation.
2ln + lnx + -1lnx = 7 + -1ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
2ln + 0 = 7 + -1ln + lnx + -1lnx
2ln = 7 + -1ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
2ln = 7 + -1ln + 0
2ln = 7 + -1ln

Solving
2ln = 7 + -1ln

Solving for variable 'l'.

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

Add 'ln' to each side of the equation.
2ln + ln = 7 + -1ln + ln

Combine like terms: 2ln + ln = 3ln
3ln = 7 + -1ln + ln

Combine like terms: -1ln + ln = 0
3ln = 7 + 0
3ln = 7

Divide each side by '3n'.
l = 2.333333333n-1

Simplifying
l = 2.333333333n-1
