What would x equal to if x equaled 4 in this: 4x

x = 4 and the expression when evaluated at x = 4, is 16.

Step-by-step explanation:

For this problem, we will simply look at the wording of the question and the given expression.  The question ask, "What would x be equal to if x equaled 4 in this: 4x?"

In the problem, we are already given that x = 4 in the following expression, so the answer to the question is x = 4.  If we were to evaluate the expression when x = 4, we would say the following:

If x = 4, then:

4x

= 4(4)

= 16

Hence, the expression would be 16 if evaluated when x = 4.
