Solving
7n = 91ahinstw

Solving for variable 'n'.

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

Add '-91ahinstw' to each side of the equation.
-91ahinstw + 7n = 91ahinstw + -91ahinstw

Combine like terms: 91ahinstw + -91ahinstw = 0
-91ahinstw + 7n = 0

Factor out the Greatest Common Factor (GCF), '7n'.
7n(-13ahistw + 1) = 0

Ignore the factor 7.

Subproblem 1

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

Subproblem 2

Set the factor '(-13ahistw + 1)' equal to zero and attempt to solve: Simplifying -13ahistw + 1 = 0 Reorder the terms: 1 + -13ahistw = 0 Solving 1 + -13ahistw = 0 Move all terms containing n to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -13ahistw = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -13ahistw = 0 + -1 -13ahistw = 0 + -1 Combine like terms: 0 + -1 = -1 -13ahistw = -1 Add '13ahistw' to each side of the equation. -13ahistw + 13ahistw = -1 + 13ahistw Combine like terms: -13ahistw + 13ahistw = 0 0 = -1 + 13ahistw Simplifying 0 = -1 + 13ahistw The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
