Solving for variable 'g'.

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

Add '-150glo' to each side of the equation.
15glox + -150glo + 21goxL = 150glo + -150glo

Reorder the terms:
-150glo + 15glox + 21goxL = 150glo + -150glo

Combine like terms: 150glo + -150glo = 0
-150glo + 15glox + 21goxL = 0

Factor out the Greatest Common Factor (GCF), '3go'.
3go(-50l + 5lx + 7xL) = 0

Ignore the factor 3.

Subproblem 1

Set the factor 'go' equal to zero and attempt to solve: Simplifying go = 0 Solving go = 0 Move all terms containing g to the left, all other terms to the right. Simplifying go = 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 '(-50l + 5lx + 7xL)' equal to zero and attempt to solve: Simplifying -50l + 5lx + 7xL = 0 Solving -50l + 5lx + 7xL = 0 Move all terms containing g to the left, all other terms to the right. Add '50l' to each side of the equation. -50l + 5lx + 50l + 7xL = 0 + 50l Reorder the terms: -50l + 50l + 5lx + 7xL = 0 + 50l Combine like terms: -50l + 50l = 0 0 + 5lx + 7xL = 0 + 50l 5lx + 7xL = 0 + 50l Remove the zero: 5lx + 7xL = 50l Add '-5lx' to each side of the equation. 5lx + -5lx + 7xL = 50l + -5lx Combine like terms: 5lx + -5lx = 0 0 + 7xL = 50l + -5lx 7xL = 50l + -5lx Add '-7xL' to each side of the equation. 7xL + -7xL = 50l + -5lx + -7xL Combine like terms: 7xL + -7xL = 0 0 = 50l + -5lx + -7xL Simplifying 0 = 50l + -5lx + -7xL 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.
