Simplifying log(4x + 7) = log(x + -8) Reorder the terms: glo(7 + 4x) = log(x + -8) (7 * glo + 4x * glo) = log(x + -8) (7glo + 4glox) = log(x + -8) Reorder the terms: 7glo + 4glox = glo(-8 + x) 7glo + 4glox = (-8 * glo + x * glo) 7glo + 4glox = (-8glo + glox) Solving 7glo + 4glox = -8glo + glox Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add '8glo' to each side of the equation. 7glo + 8glo + 4glox = -8glo + 8glo + glox Combine like terms: 7glo + 8glo = 15glo 15glo + 4glox = -8glo + 8glo + glox Combine like terms: -8glo + 8glo = 0 15glo + 4glox = 0 + glox 15glo + 4glox = glox Add '-1glox' to each side of the equation. 15glo + 4glox + -1glox = glox + -1glox Combine like terms: 4glox + -1glox = 3glox 15glo + 3glox = glox + -1glox Combine like terms: glox + -1glox = 0 15glo + 3glox = 0 Factor out the Greatest Common Factor (GCF), '3glo'. 3glo(5 + x) = 0 Ignore the factor 3.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 '(5 + x)' equal to zero and attempt to solve: Simplifying 5 + x = 0 Solving 5 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + x = 0 + -5 x = 0 + -5 Combine like terms: 0 + -5 = -5 x = -5 Add '-1x' to each side of the equation. x + -1x = -5 + -1x Combine like terms: x + -1x = 0 0 = -5 + -1x Simplifying 0 = -5 + -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.
