r=rt

Solution for r=rt equation:

Simplifying
r = rt

Solving
r = rt

Solving for variable 'r'.

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

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

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

Factor out the Greatest Common Factor (GCF), 'r'.
r(1 + -1t) = 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 + -1t)' equal to zero and attempt to solve:

Simplifying
1 + -1t = 0

Solving
1 + -1t = 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 + -1t = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -1t = 0 + -1
-1t = 0 + -1

Combine like terms: 0 + -1 = -1
-1t = -1

Add 't' to each side of the equation.
-1t + t = -1 + t

Combine like terms: -1t + t = 0
0 = -1 + t

Simplifying
0 = -1 + t
