To show the distributive property, you need to distribute the number outside the parentheses to all the terms inside.
In this case, the number outside the parentheses is 7. So, distributing 7 to 2 and 4, we get:
7(2+4) = 7(6) = 42.
Now, the expression becomes 42 + 14 + x.
To simplify further, we combine the constant terms:
42 + 14 = 56.
The expression now becomes 56 + x.
So, we have: 56 + x.
Therefore, x can be any number.
