P-3(r-p)=

Solution for P-3(r-p)= equation:

Simplifying
P + -3(r + -1p) = 0

Reorder the terms:
P + -3(-1p + r) = 0
P + (-1p * -3 + r * -3) = 0
P + (3p + -3r) = 0

Solving
P + 3p + -3r = 0

Solving for variable 'P'.

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

Add '-3p' to each side of the equation.
P + 3p + -3p + -3r = 0 + -3p

Combine like terms: 3p + -3p = 0
P + 0 + -3r = 0 + -3p
P + -3r = 0 + -3p
Remove the zero:
P + -3r = -3p

Add '3r' to each side of the equation.
P + -3r + 3r = -3p + 3r

Combine like terms: -3r + 3r = 0
P + 0 = -3p + 3r
P = -3p + 3r

Simplifying
P = -3p + 3r
