Simplifying
log[4](x) + log[4](x + -3) = log[4](-7x + 21)

Reorder the terms for easier multiplication:
4glo * x + log[4](x + -3) = log[4](-7x + 21)

Multiply glo * x
4glox + log[4](x + -3) = log[4](-7x + 21)

Reorder the terms:
4glox + glo * 4(-3 + x) = log[4](-7x + 21)

Reorder the terms for easier multiplication:
4glox + 4glo(-3 + x) = log[4](-7x + 21)
4glox + (-3 * 4glo + x * 4glo) = log[4](-7x + 21)
4glox + (-12glo + 4glox) = log[4](-7x + 21)

Reorder the terms:
-12glo + 4glox + 4glox = log[4](-7x + 21)

Combine like terms: 4glox + 4glox = 8glox
-12glo + 8glox = log[4](-7x + 21)

Reorder the terms:
-12glo + 8glox = glo * 4(21 + -7x)

Reorder the terms for easier multiplication:
-12glo + 8glox = 4glo(21 + -7x)
-12glo + 8glox = (21 * 4glo + -7x * 4glo)
-12glo + 8glox = (84glo + -28glox)

Solving
-12glo + 8glox = 84glo + -28glox

Solving for variable 'g'.

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

Add '-84glo' to each side of the equation.
-12glo + -84glo + 8glox = 84glo + -84glo + -28glox

Combine like terms: -12glo + -84glo = -96glo
-96glo + 8glox = 84glo + -84glo + -28glox

Combine like terms: 84glo + -84glo = 0
-96glo + 8glox = 0 + -28glox
-96glo + 8glox = -28glox

Add '28glox' to each side of the equation.
-96glo + 8glox + 28glox = -28glox + 28glox

Combine like terms: 8glox + 28glox = 36glox
-96glo + 36glox = -28glox + 28glox

Combine like terms: -28glox + 28glox = 0
-96glo + 36glox = 0

Factor out the Greatest Common Factor (GCF), '12glo'.
12glo(-8 + 3x) = 0

Ignore the factor 12.

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.
