Solution for ln(x)+ln(x+1)=ln(2x+6) equation:


Simplifying
ln(x) + ln(x + 1) = ln(2x + 6)

Multiply ln * x
lnx + ln(x + 1) = ln(2x + 6)

Reorder the terms:
lnx + ln(1 + x) = ln(2x + 6)
lnx + (1 * ln + x * ln) = ln(2x + 6)
lnx + (1ln + lnx) = ln(2x + 6)

Reorder the terms:
1ln + lnx + lnx = ln(2x + 6)

Combine like terms: lnx + lnx = 2lnx
1ln + 2lnx = ln(2x + 6)

Reorder the terms:
1ln + 2lnx = ln(6 + 2x)
1ln + 2lnx = (6 * ln + 2x * ln)
1ln + 2lnx = (6ln + 2lnx)

Add '-2lnx' to each side of the equation.
1ln + 2lnx + -2lnx = 6ln + 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
1ln + 0 = 6ln + 2lnx + -2lnx
1ln = 6ln + 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
1ln = 6ln + 0
1ln = 6ln

Solving
1ln = 6ln

Solving for variable 'l'.

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

Add '-6ln' to each side of the equation.
1ln + -6ln = 6ln + -6ln

Combine like terms: 1ln + -6ln = -5ln
-5ln = 6ln + -6ln

Combine like terms: 6ln + -6ln = 0
-5ln = 0

Divide each side by '-5'.
ln = 0

Simplifying
ln = 0
