Simplifying (r42) + -4r = 0 r42 + -4r = 0 Reorder the terms: -4r + r42 = 0 Solving -4r + r42 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), 'r'. r(-4 + r41) = 0Subproblem 1
Set the factor 'r' equal to zero and attempt to solve: Simplifying r = 0 Solving r = 0 Move all terms containing r to the left, all other terms to the right. Simplifying r = 0Subproblem 2
Set the factor '(-4 + r41)' equal to zero and attempt to solve: Simplifying -4 + r41 = 0 Solving -4 + r41 = 0 Move all terms containing r to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + r41 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + r41 = 0 + 4 r41 = 0 + 4 Combine like terms: 0 + 4 = 4 r41 = 4 Simplifying r41 = 4 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
