63glo + (-35glo + 28glox2) = log(7) * 21

Combine like terms: 63glo + -35glo = 28glo
28glo + 28glox2 = log(7) * 21

Reorder the terms for easier multiplication:
28glo + 28glox2 = 7 * 21glo

Multiply 7 * 21
28glo + 28glox2 = 147glo

Solving
28glo + 28glox2 = 147glo

Solving for variable 'g'.

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

Add '-147glo' to each side of the equation.
28glo + -147glo + 28glox2 = 147glo + -147glo

Combine like terms: 28glo + -147glo = -119glo
-119glo + 28glox2 = 147glo + -147glo

Combine like terms: 147glo + -147glo = 0
-119glo + 28glox2 = 0

Factor out the Greatest Common Factor (GCF), '7glo'.
7glo(-17 + 4x2) = 0

Ignore the factor 7.

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.
