Solution for ln(x+7)+ln(x-3)=2ln(x) equation:


Simplifying
ln(x + 7) + ln(x + -3) = 2ln(x)

Reorder the terms:
ln(7 + x) + ln(x + -3) = 2ln(x)
(7 * ln + x * ln) + ln(x + -3) = 2ln(x)
(7ln + lnx) + ln(x + -3) = 2ln(x)

Reorder the terms:
7ln + lnx + ln(-3 + x) = 2ln(x)
7ln + lnx + (-3 * ln + x * ln) = 2ln(x)
7ln + lnx + (-3ln + lnx) = 2ln(x)

Reorder the terms:
7ln + -3ln + lnx + lnx = 2ln(x)

Combine like terms: 7ln + -3ln = 4ln
4ln + lnx + lnx = 2ln(x)

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

Multiply ln * x
4ln + 2lnx = 2lnx

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

Combine like terms: 2lnx + -2lnx = 0
4ln + 0 = 2lnx + -2lnx
4ln = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
4ln = 0

Solving
4ln = 0

Solving for variable 'l'.

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

Divide each side by '4'.
ln = 0

Simplifying
ln = 0
