Solving
30glo + 18glox = 2 + 10glo + 2glox

Solving for variable 'g'.

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

Add '-10glo' to each side of the equation.
30glo + -10glo + 18glox = 2 + 10glo + -10glo + 2glox

Combine like terms: 30glo + -10glo = 20glo
20glo + 18glox = 2 + 10glo + -10glo + 2glox

Combine like terms: 10glo + -10glo = 0
20glo + 18glox = 2 + 0 + 2glox
20glo + 18glox = 2 + 2glox

Add '-2glox' to each side of the equation.
20glo + 18glox + -2glox = 2 + 2glox + -2glox

Combine like terms: 18glox + -2glox = 16glox
20glo + 16glox = 2 + 2glox + -2glox

Combine like terms: 2glox + -2glox = 0
20glo + 16glox = 2 + 0
20glo + 16glox = 2

Reorder the terms:
-2 + 20glo + 16glox = 2 + -2

Combine like terms: 2 + -2 = 0
-2 + 20glo + 16glox = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(-1 + 10glo + 8glox) = 0

Ignore the factor 2.

Subproblem 1

Set the factor '(-1 + 10glo + 8glox)' equal to zero and attempt to solve: Simplifying -1 + 10glo + 8glox = 0 Solving -1 + 10glo + 8glox = 0 Move all terms containing g to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 10glo + 1 + 8glox = 0 + 1 Reorder the terms: -1 + 1 + 10glo + 8glox = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 10glo + 8glox = 0 + 1 10glo + 8glox = 0 + 1 Combine like terms: 0 + 1 = 1 10glo + 8glox = 1 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.
