Stephen · Answer 1

Since we have P = 2a + 2b we can do the following to make b the subject of the formula

P = 2a + 2b (Minus 2a from both sides)

P - 2a = 2b (Divide both sides by 2)

(P - 2a) / 2 = b

or

(p / 2) - a = b

Pollard · Answer 2

My answer is: P/2a = 2b

if that's wrong then im sorry I got it by dividing 2a on each side so 2b would be alone
