Solution for ln(x+6)+ln(x-3)=ln(10) equation:


Simplifying
ln(x + 6) + ln(x + -3) = ln(10)

Reorder the terms:
ln(6 + x) + ln(x + -3) = ln(10)
(6 * ln + x * ln) + ln(x + -3) = ln(10)
(6ln + lnx) + ln(x + -3) = ln(10)

Reorder the terms:
6ln + lnx + ln(-3 + x) = ln(10)
6ln + lnx + (-3 * ln + x * ln) = ln(10)
6ln + lnx + (-3ln + lnx) = ln(10)

Reorder the terms:
6ln + -3ln + lnx + lnx = ln(10)

Combine like terms: 6ln + -3ln = 3ln
3ln + lnx + lnx = ln(10)

Combine like terms: lnx + lnx = 2lnx
3ln + 2lnx = ln(10)

Reorder the terms for easier multiplication:
3ln + 2lnx = 10ln

Solving
3ln + 2lnx = 10ln

Solving for variable 'l'.

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

Add '-10ln' to each side of the equation.
3ln + -10ln + 2lnx = 10ln + -10ln

Combine like terms: 3ln + -10ln = -7ln
-7ln + 2lnx = 10ln + -10ln

Combine like terms: 10ln + -10ln = 0
-7ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-7 + 2x) = 0

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-7 + 2x)' equal to zero and attempt to solve: Simplifying -7 + 2x = 0 Solving -7 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + 2x = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 2x = 0 + 7 2x = 0 + 7 Combine like terms: 0 + 7 = 7 2x = 7 Add '-2x' to each side of the equation. 2x + -2x = 7 + -2x Combine like terms: 2x + -2x = 0 0 = 7 + -2x Simplifying 0 = 7 + -2x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
