Simplifying k(10 + -7r) = 0 (10 * k + -7r * k) = 0 (10k + -7kr) = 0 Solving 10k + -7kr = 0 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), 'k'. k(10 + -7r) = 0Subproblem 1
Set the factor 'k' equal to zero and attempt to solve: Simplifying k = 0 Solving k = 0 Move all terms containing k to the left, all other terms to the right. Simplifying k = 0Subproblem 2
Set the factor '(10 + -7r)' equal to zero and attempt to solve: Simplifying 10 + -7r = 0 Solving 10 + -7r = 0 Move all terms containing k to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + -7r = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -7r = 0 + -10 -7r = 0 + -10 Combine like terms: 0 + -10 = -10 -7r = -10 Add '7r' to each side of the equation. -7r + 7r = -10 + 7r Combine like terms: -7r + 7r = 0 0 = -10 + 7r Simplifying 0 = -10 + 7r The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
