Solving for variable 'x'.

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

Add '-81ahistwx' to each side of the equation.
-81ahistwx + 3x = 81ahistwx + -81ahistwx

Combine like terms: 81ahistwx + -81ahistwx = 0
-81ahistwx + 3x = 0

Factor out the Greatest Common Factor (GCF), '3x'.
3x(-27ahistw + 1) = 0

Ignore the factor 3.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-27ahistw + 1)' equal to zero and attempt to solve: Simplifying -27ahistw + 1 = 0 Reorder the terms: 1 + -27ahistw = 0 Solving 1 + -27ahistw = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -27ahistw = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -27ahistw = 0 + -1 -27ahistw = 0 + -1 Combine like terms: 0 + -1 = -1 -27ahistw = -1 Add '27ahistw' to each side of the equation. -27ahistw + 27ahistw = -1 + 27ahistw Combine like terms: -27ahistw + 27ahistw = 0 0 = -1 + 27ahistw Simplifying 0 = -1 + 27ahistw The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
