Solution for Prt=r equation:


Simplifying
Prt = r

Solving
rtP = r

Solving for variable 'r'.

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

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

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

Factor out the Greatest Common Factor (GCF), 'r'.
r(-1 + tP) = 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 '(-1 + tP)' equal to zero and attempt to solve: Simplifying -1 + tP = 0 Solving -1 + tP = 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 + tP = 0 + 1 Combine like terms: -1 + 1 = 0 0 + tP = 0 + 1 tP = 0 + 1 Combine like terms: 0 + 1 = 1 tP = 1 Add '-1tP' to each side of the equation. tP + -1tP = 1 + -1tP Combine like terms: tP + -1tP = 0 0 = 1 + -1tP Simplifying 0 = 1 + -1tP The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Solution

r = {0}
