Answer:
81=5+b, 81-5=b, 81-b=5
Step-by-step 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.
