Solution for ln(x-25)+ln(x+48)=3ln(4) equation:


Simplifying
ln(x + -25) + ln(x + 48) = 3ln(4)

Reorder the terms:
ln(-25 + x) + ln(x + 48) = 3ln(4)
(-25 * ln + x * ln) + ln(x + 48) = 3ln(4)
(-25ln + lnx) + ln(x + 48) = 3ln(4)

Reorder the terms:
-25ln + lnx + ln(48 + x) = 3ln(4)
-25ln + lnx + (48 * ln + x * ln) = 3ln(4)
-25ln + lnx + (48ln + lnx) = 3ln(4)

Reorder the terms:
-25ln + 48ln + lnx + lnx = 3ln(4)

Combine like terms: -25ln + 48ln = 23ln
23ln + lnx + lnx = 3ln(4)

Combine like terms: lnx + lnx = 2lnx
23ln + 2lnx = 3ln(4)

Reorder the terms for easier multiplication:
23ln + 2lnx = 3 * 4ln

Multiply 3 * 4
23ln + 2lnx = 12ln

Solving
23ln + 2lnx = 12ln

Solving for variable 'l'.

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

Add '-12ln' to each side of the equation.
23ln + -12ln + 2lnx = 12ln + -12ln

Combine like terms: 23ln + -12ln = 11ln
11ln + 2lnx = 12ln + -12ln

Combine like terms: 12ln + -12ln = 0
11ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(11 + 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 '(11 + 2x)' equal to zero and attempt to solve: Simplifying 11 + 2x = 0 Solving 11 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + 2x = 0 + -11 Combine like terms: 11 + -11 = 0 0 + 2x = 0 + -11 2x = 0 + -11 Combine like terms: 0 + -11 = -11 2x = -11 Add '-2x' to each side of the equation. 2x + -2x = -11 + -2x Combine like terms: 2x + -2x = 0 0 = -11 + -2x Simplifying 0 = -11 + -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.
