Answer:

81=5+b, 81-5=b, 81-b=5

Explanation:

We can write the equation in terms of 81, b, or 5. Let's first start by writing it in terms of 81. We are already given that 5+b=81 therefore...

5+b=81 OR 81=5+b (transitive property)

Now, let's write the equation in terms of b.

5+b=81

Subtract 5 from both sides (subtraction property of equality)

5-5+b=81-5

b=81-5 OR 81-5=b (transitive property)

Lastly, let's write the equation in terms of 5.

5+b=81

Subtract b from both sides (subtraction property of equality)

5+b-b=81-b

5=81-b OR 81-b=5 (transitive property.
