Solution for (Pi)=2(pi)r equation: 


Simplifying
(Pi) = 2(pi) * r
iP = 2(pi) * r

Multiply ip * r
iP = 2ipr

Solving
iP = 2ipr

Solving for variable 'i'.

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

Add '-2ipr' to each side of the equation.
iP + -2ipr = 2ipr + -2ipr

Combine like terms: 2ipr + -2ipr = 0
iP + -2ipr = 0

Factor out the Greatest Common Factor (GCF), 'i'.
i(P + -2pr) = 0


Subproblem 1
Set the factor 'i' equal to zero and attempt to solve:

Simplifying
i = 0

Solving
i = 0

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

Simplifying
i = 0

Subproblem 2
Set the factor '(P + -2pr)' equal to zero and attempt to solve:

Simplifying
P + -2pr = 0

Solving
P + -2pr = 0

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

Add '-1P' to each side of the equation.
P + -1P + -2pr = 0 + -1P

Combine like terms: P + -1P = 0
0 + -2pr = 0 + -1P
-2pr = 0 + -1P
Remove the zero:
-2pr = -1P

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

Combine like terms: -2pr + 2pr = 0
0 = -1P + 2pr

Simplifying
0 = -1P + 2pr
