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 '(-2.5 + E)' equal to zero and attempt to solve: Simplifying -2.5 + E = 0 Solving -2.5 + E = 0 Move all terms containing n to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + E = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + E = 0 + 2.5 E = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 E = 2.5 Add '-1E' to each side of the equation. E + -1E = 2.5 + -1E Combine like terms: E + -1E = 0 0 = 2.5 + -1E Simplifying 0 = 2.5 + -1E The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
