Answer:

A. 20

Step-by-step explanation:

Firstly, you have an equation where x is unknown.

It is said to find the result of this equation if x is 5.

That means you have to substitute 5 instead of x in your equation.

That will be:

3*5+4*5-15

When you calculate that, you get number 20.

Need the answer on this

denpristay [2]

None of the answers are correct because it’s definitely not “Given” because x=20 is like an answer. It’s also not “Distributive Property”, “subtraction Property”, and or “Additional Property” b/c there’s nothing that can be distributed, subtract or add. It’s just an answer.
