Solution for =ln(3x-9) equation:


Simplifying
0 = ln(3x + -9)

Reorder the terms:
0 = ln(-9 + 3x)
0 = (-9 * ln + 3x * ln)
0 = (-9ln + 3lnx)

Solving
0 = -9ln + 3lnx

Solving for variable 'l'.

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

Add '9ln' to each side of the equation.
0 + 9ln = -9ln + 9ln + 3lnx
Remove the zero:
9ln = -9ln + 9ln + 3lnx

Combine like terms: -9ln + 9ln = 0
9ln = 0 + 3lnx
9ln = 3lnx

Add '-3lnx' to each side of the equation.
9ln + -3lnx = 3lnx + -3lnx

Combine like terms: 3lnx + -3lnx = 0
9ln + -3lnx = 0

Factor out the Greatest Common Factor (GCF), '3ln'.
3ln(3 + -1x) = 0

Ignore the factor 3.

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 '(3 + -1x)' equal to zero and attempt to solve: Simplifying 3 + -1x = 0 Solving 3 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -1x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1x = 0 + -3 -1x = 0 + -3 Combine like terms: 0 + -3 = -3 -1x = -3 Add 'x' to each side of the equation. -1x + x = -3 + x Combine like terms: -1x + x = 0 0 = -3 + x Simplifying 0 = -3 + x 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.
