Answer & Step-by-step explanation:
Mathematical Problem Example : 100 x 105
By commutative rule, a x b = b x a : 100 x 105 = 105 x 100 = 10500
By distributive rule, a x (b+c) = (a x b) + (a x c)
Breaking down 105, we get : 100 x 105 = 100 (100 + 5)
= (100 x 100) + (100 x 5) = 10000 + 500 = 10500
As solutions by both rules are same, algebra multiple ways to solve a mathematical problem have been hence proved.

Answer:
L = P/2 - W
Explanation:
Step 1 - Start by factoring out the two
P = 2L + 2W
P = 2(L + W)
Step 2 - Divide both sides of the equation by two
P = 2(L + W)
P/ 2 = 2(L + W)/ 2
P/ 2 = L + W
Step 3 - Subtract W from both sides of the equation
P/ 2 = L + W
P/ 2 - W = L + W - W
P/ 2 - W = L
