Simplifying logx + log(x + -18) = log(3x) Reorder the terms: glox + glo(-18 + x) = log(3x) glox + (-18 * glo + x * glo) = log(3x) glox + (-18glo + glox) = log(3x) Reorder the terms: -18glo + glox + glox = log(3x) Combine like terms: glox + glox = 2glox -18glo + 2glox = log(3x) Remove parenthesis around (3x) -18glo + 2glox = glo * 3x Reorder the terms for easier multiplication: -18glo + 2glox = 3glo * x Multiply glo * x -18glo + 2glox = 3glox Solving -18glo + 2glox = 3glox Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add '-3glox' to each side of the equation. -18glo + 2glox + -3glox = 3glox + -3glox Combine like terms: 2glox + -3glox = -1glox -18glo + -1glox = 3glox + -3glox Combine like terms: 3glox + -3glox = 0 -18glo + -1glox = 0 Factor out the Greatest Common Factor (GCF), '-1glo'. -1glo(18 + x) = 0 Ignore the factor -1.Subproblem 1
Set the factor 'glo' equal to zero and attempt to solve: Simplifying glo = 0 Solving glo = 0 Move all terms containing g to the left, all other terms to the right. Simplifying glo = 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 '(18 + x)' equal to zero and attempt to solve: Simplifying 18 + x = 0 Solving 18 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '-18' to each side of the equation. 18 + -18 + x = 0 + -18 Combine like terms: 18 + -18 = 0 0 + x = 0 + -18 x = 0 + -18 Combine like terms: 0 + -18 = -18 x = -18 Add '-1x' to each side of the equation. x + -1x = -18 + -1x Combine like terms: x + -1x = 0 0 = -18 + -1x Simplifying 0 = -18 + -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.
