18glox = 9glo(15 + x) + log[9] * 4(4)
18glox = (15 * 9glo + x * 9glo) + log[9] * 4(4)
18glox = (135glo + 9glox) + log[9] * 4(4)

Reorder the terms for easier multiplication:
18glox = 135glo + 9glox + 9 * 4 * 4glo

Multiply 9 * 4
18glox = 135glo + 9glox + 36 * 4glo

Multiply 36 * 4
18glox = 135glo + 9glox + 144glo

Reorder the terms:
18glox = 135glo + 144glo + 9glox

Combine like terms: 135glo + 144glo = 279glo
18glox = 279glo + 9glox

Solving
18glox = 279glo + 9glox

Solving for variable 'g'.

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

Add '-279glo' to each side of the equation.
-279glo + 18glox = 279glo + -279glo + 9glox

Combine like terms: 279glo + -279glo = 0
-279glo + 18glox = 0 + 9glox
-279glo + 18glox = 9glox

Add '-9glox' to each side of the equation.
-279glo + 18glox + -9glox = 9glox + -9glox

Combine like terms: 18glox + -9glox = 9glox
-279glo + 9glox = 9glox + -9glox

Combine like terms: 9glox + -9glox = 0
-279glo + 9glox = 0

Factor out the Greatest Common Factor (GCF), '9glo'.
9glo(-31 + x) = 0

Ignore the factor 9.

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 '(-31 + x)' equal to zero and attempt to solve: Simplifying -31 + x = 0 Solving -31 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '31' to each side of the equation. -31 + 31 + x = 0 + 31 Combine like terms: -31 + 31 = 0 0 + x = 0 + 31 x = 0 + 31 Combine like terms: 0 + 31 = 31 x = 31 Add '-1x' to each side of the equation. x + -1x = 31 + -1x Combine like terms: x + -1x = 0 0 = 31 + -1x Simplifying 0 = 31 + -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.
