Solution for r=prt equation:


Simplifying
r = prt

Solving
r = prt

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-1prt' to each side of the equation.
-1prt + r = prt + -1prt

Combine like terms: prt + -1prt = 0
-1prt + r = 0

Factor out the Greatest Common Factor (GCF), 'r'.
r(-1pt + 1) = 0

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 '(-1pt + 1)' equal to zero and attempt to solve: Simplifying -1pt + 1 = 0 Reorder the terms: 1 + -1pt = 0 Solving 1 + -1pt = 0 Move all terms containing r to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1pt = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1pt = 0 + -1 -1pt = 0 + -1 Combine like terms: 0 + -1 = -1 -1pt = -1 Add 'pt' to each side of the equation. -1pt + pt = -1 + pt Combine like terms: -1pt + pt = 0 0 = -1 + pt Simplifying 0 = -1 + pt The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Solution

r = {0}
