Solution for log(3r+7)=log(9-4r) equation:


Simplifying
log(3r + 7) = log(9 + -4r)

Reorder the terms:
glo(7 + 3r) = log(9 + -4r)
(7 * glo + 3r * glo) = log(9 + -4r)
(7glo + 3glor) = log(9 + -4r)
7glo + 3glor = (9 * glo + -4r * glo)
7glo + 3glor = (9glo + -4glor)

Solving
7glo + 3glor = 9glo + -4glor

Solving for variable 'g'.

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

Add '-9glo' to each side of the equation.
7glo + -9glo + 3glor = 9glo + -9glo + -4glor

Combine like terms: 7glo + -9glo = -2glo
-2glo + 3glor = 9glo + -9glo + -4glor

Combine like terms: 9glo + -9glo = 0
-2glo + 3glor = 0 + -4glor
-2glo + 3glor = -4glor

Add '4glor' to each side of the equation.
-2glo + 3glor + 4glor = -4glor + 4glor

Combine like terms: 3glor + 4glor = 7glor
-2glo + 7glor = -4glor + 4glor

Combine like terms: -4glor + 4glor = 0
-2glo + 7glor = 0

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(-2 + 7r) = 0

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 '(-2 + 7r)' equal to zero and attempt to solve: Simplifying -2 + 7r = 0 Solving -2 + 7r = 0 Move all terms containing g to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + 7r = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 7r = 0 + 2 7r = 0 + 2 Combine like terms: 0 + 2 = 2 7r = 2 Add '-7r' to each side of the equation. 7r + -7r = 2 + -7r Combine like terms: 7r + -7r = 0 0 = 2 + -7r Simplifying 0 = 2 + -7r 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.
