Solution for ln(x+3)+ln(x)=ln(28) equation:


Simplifying
ln(x + 3) + ln(x) = ln(28)

Reorder the terms:
ln(3 + x) + ln(x) = ln(28)
(3 * ln + x * ln) + ln(x) = ln(28)
(3ln + lnx) + ln(x) = ln(28)

Multiply ln * x
3ln + lnx + lnx = ln(28)

Combine like terms: lnx + lnx = 2lnx
3ln + 2lnx = ln(28)

Reorder the terms for easier multiplication:
3ln + 2lnx = 28ln

Solving
3ln + 2lnx = 28ln

Solving for variable 'l'.

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

Add '-28ln' to each side of the equation.
3ln + -28ln + 2lnx = 28ln + -28ln

Combine like terms: 3ln + -28ln = -25ln
-25ln + 2lnx = 28ln + -28ln

Combine like terms: 28ln + -28ln = 0
-25ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-25 + 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 '(-25 + 2x)' equal to zero and attempt to solve: Simplifying -25 + 2x = 0 Solving -25 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '25' to each side of the equation. -25 + 25 + 2x = 0 + 25 Combine like terms: -25 + 25 = 0 0 + 2x = 0 + 25 2x = 0 + 25 Combine like terms: 0 + 25 = 25 2x = 25 Add '-2x' to each side of the equation. 2x + -2x = 25 + -2x Combine like terms: 2x + -2x = 0 0 = 25 + -2x Simplifying 0 = 25 + -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.
