Simplifying 4xn = 21n Solving 4nx = 21n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-21n' to each side of the equation. -21n + 4nx = 21n + -21n Combine like terms: 21n + -21n = 0 -21n + 4nx = 0 Factor out the Greatest Common Factor (GCF), 'n'. n(-21 + 4x) = 0Subproblem 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 = 0Subproblem 2
Set the factor '(-21 + 4x)' equal to zero and attempt to solve: Simplifying -21 + 4x = 0 Solving -21 + 4x = 0 Move all terms containing n to the left, all other terms to the right. Add '21' to each side of the equation. -21 + 21 + 4x = 0 + 21 Combine like terms: -21 + 21 = 0 0 + 4x = 0 + 21 4x = 0 + 21 Combine like terms: 0 + 21 = 21 4x = 21 Add '-4x' to each side of the equation. 4x + -4x = 21 + -4x Combine like terms: 4x + -4x = 0 0 = 21 + -4x Simplifying 0 = 21 + -4x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
