4glo(-5 + 2x) = log[4](x + 5)
(-5 * 4glo + 2x * 4glo) = log[4](x + 5)
(-20glo + 8glox) = log[4](x + 5)

Reorder the terms:
-20glo + 8glox = glo * 4(5 + x)

Reorder the terms for easier multiplication:
-20glo + 8glox = 4glo(5 + x)
-20glo + 8glox = (5 * 4glo + x * 4glo)
-20glo + 8glox = (20glo + 4glox)

Solving
-20glo + 8glox = 20glo + 4glox

Solving for variable 'g'.

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

Add '-20glo' to each side of the equation.
-20glo + -20glo + 8glox = 20glo + -20glo + 4glox

Combine like terms: -20glo + -20glo = -40glo
-40glo + 8glox = 20glo + -20glo + 4glox

Combine like terms: 20glo + -20glo = 0
-40glo + 8glox = 0 + 4glox
-40glo + 8glox = 4glox

Add '-4glox' to each side of the equation.
-40glo + 8glox + -4glox = 4glox + -4glox

Combine like terms: 8glox + -4glox = 4glox
-40glo + 4glox = 4glox + -4glox

Combine like terms: 4glox + -4glox = 0
-40glo + 4glox = 0

Factor out the Greatest Common Factor (GCF), '4glo'.
4glo(-10 + x) = 0

Ignore the factor 4.

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 '(-10 + x)' equal to zero and attempt to solve: Simplifying -10 + x = 0 Solving -10 + x = 0 Move all terms containing g 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.
