Simplifying rd = 309d Solving dr = 309d Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-309d' to each side of the equation. -309d + dr = 309d + -309d Combine like terms: 309d + -309d = 0 -309d + dr = 0 Factor out the Greatest Common Factor (GCF), 'd'. d(-309 + r) = 0Subproblem 1
Set the factor 'd' equal to zero and attempt to solve: Simplifying d = 0 Solving d = 0 Move all terms containing d to the left, all other terms to the right. Simplifying d = 0Subproblem 2
Set the factor '(-309 + r)' equal to zero and attempt to solve: Simplifying -309 + r = 0 Solving -309 + r = 0 Move all terms containing d to the left, all other terms to the right. Add '309' to each side of the equation. -309 + 309 + r = 0 + 309 Combine like terms: -309 + 309 = 0 0 + r = 0 + 309 r = 0 + 309 Combine like terms: 0 + 309 = 309 r = 309 Add '-1r' to each side of the equation. r + -1r = 309 + -1r Combine like terms: r + -1r = 0 0 = 309 + -1r Simplifying 0 = 309 + -1r The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
