r=2nr

Solution for r=2nr equation:

Simplifying
r = 2nr

Solving
r = 2nr

Solving for variable 'r'.

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

Add '-2nr' to each side of the equation.
-2nr + r = 2nr + -2nr

Combine like terms: 2nr + -2nr = 0
-2nr + r = 0

Factor out the Greatest Common Factor (GCF), 'r'.
r(-2n + 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 '(-2n + 1)' equal to zero and attempt to solve:

Simplifying
-2n + 1 = 0

Reorder the terms:
1 + -2n = 0

Solving
1 + -2n = 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 + -2n = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -2n = 0 + -1
-2n = 0 + -1

Combine like terms: 0 + -1 = -1
-2n = -1

Add '2n' to each side of the equation.
-2n + 2n = -1 + 2n

Combine like terms: -2n + 2n = 0
0 = -1 + 2n

Simplifying
0 = -1 + 2n
