(-1bglo + bglox) = 2logb(x + -1)

Reorder the terms:
-1bglo + bglox = 2bglo(-1 + x)
-1bglo + bglox = (-1 * 2bglo + x * 2bglo)
-1bglo + bglox = (-2bglo + 2bglox)

Solving
-1bglo + bglox = -2bglo + 2bglox

Solving for variable 'b'.

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

Add '2bglo' to each side of the equation.
-1bglo + 2bglo + bglox = -2bglo + 2bglo + 2bglox

Combine like terms: -1bglo + 2bglo = 1bglo
1bglo + bglox = -2bglo + 2bglo + 2bglox

Combine like terms: -2bglo + 2bglo = 0
1bglo + bglox = 0 + 2bglox
1bglo + bglox = 2bglox

Add '-2bglox' to each side of the equation.
1bglo + bglox + -2bglox = 2bglox + -2bglox

Combine like terms: bglox + -2bglox = -1bglox
1bglo + -1bglox = 2bglox + -2bglox

Combine like terms: 2bglox + -2bglox = 0
1bglo + -1bglox = 0

Factor out the Greatest Common Factor (GCF), 'bglo'.
bglo(1 + -1x) = 0

Subproblem 1

Set the factor 'bglo' equal to zero and attempt to solve: Simplifying bglo = 0 Solving bglo = 0 Move all terms containing b to the left, all other terms to the right.
