Answer:
4x and 15+x have the same value when x is 5.
Explanation:
To understand why 4x and 15+x have the same value when x is 5, we need to evaluate both expressions for the given value of x.
Let's first calculate 4x when x is 5. Then, Then, we substitute 5 for x in the expression 4x:
4x = 4(5) = 20
Now, let's calculate 15+x when x is 5. We substitute 5 for x in the expression 15+x:
15+x = 15+5 = 20
As we can see, both expressions evaluate to 20 when x is 5. Therefore, we can conclude that 4x and 15+x have the same value when x is 5.
