Simplifying ln(6x + 40) = ln(3x + 10) Reorder the terms: ln(40 + 6x) = ln(3x + 10) (40 * ln + 6x * ln) = ln(3x + 10) (40ln + 6lnx) = ln(3x + 10) Reorder the terms: 40ln + 6lnx = ln(10 + 3x) 40ln + 6lnx = (10 * ln + 3x * ln) 40ln + 6lnx = (10ln + 3lnx) Solving 40ln + 6lnx = 10ln + 3lnx 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. 40ln + -10ln + 6lnx = 10ln + -10ln + 3lnx Combine like terms: 40ln + -10ln = 30ln 30ln + 6lnx = 10ln + -10ln + 3lnx Combine like terms: 10ln + -10ln = 0 30ln + 6lnx = 0 + 3lnx 30ln + 6lnx = 3lnx Add '-3lnx' to each side of the equation. 30ln + 6lnx + -3lnx = 3lnx + -3lnx Combine like terms: 6lnx + -3lnx = 3lnx 30ln + 3lnx = 3lnx + -3lnx Combine like terms: 3lnx + -3lnx = 0 30ln + 3lnx = 0 Factor out the Greatest Common Factor (GCF), '3ln'. 3ln(10 + x) = 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 '(10 + x)' equal to zero and attempt to solve: Simplifying 10 + x = 0 Solving 10 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = 0 + -10 Combine like terms: 10 + -10 = 0 0 + x = 0 + -10 x = 0 + -10 Combine like terms: 0 + -10 = -10 x = -10 Add '-1x' to each side of the equation. x + -1x = -10 + -1x Combine like terms: x + -1x = 0 0 = -10 + -1x Simplifying 0 = -10 + -1x 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.
