Subproblem 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 = 0

Subproblem 2

Set the factor '(-6t + -1r)' equal to zero and attempt to solve: Simplifying -6t + -1r = 0 Reorder the terms: -1r + -6t = 0 Solving -1r + -6t = 0 Move all terms containing r to the left, all other terms to the right. Add '6t' to each side of the equation. -1r + -6t + 6t = 0 + 6t Combine like terms: -6t + 6t = 0 -1r + 0 = 0 + 6t -1r = 0 + 6t Remove the zero: -1r = 6t Divide each side by '-1'. r = -6t Simplifying r = -6t

Subproblem 3

Set the factor '(2t + -1r)' equal to zero and attempt to solve: Simplifying 2t + -1r = 0 Reorder the terms: -1r + 2t = 0 Solving -1r + 2t = 0 Move all terms containing r to the left, all other terms to the right. Add '-2t' to each side of the equation. -1r + 2t + -2t = 0 + -2t Combine like terms: 2t + -2t = 0 -1r + 0 = 0 + -2t -1r = 0 + -2t Remove the zero: -1r = -2t Divide each side by '-1'. r = 2t Simplifying r = 2t

Solution

r = {0, -6t, 2t}
