P=2L+2(P-L)

Solution for P=2L+2(P-L) equation:

Simplifying
P = 2L + 2(P + -1L)

Reorder the terms:
P = 2L + 2(-1L + P)
P = 2L + (-1L * 2 + P * 2)
P = 2L + (-2L + 2P)

Combine like terms: 2L + -2L = 0
P = 0 + 2P
P = 2P

Solving
P = 2P

Solving for variable 'P'.

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

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

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

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

Divide each side by '-1'.
P = 0

Simplifying
P = 0
