Answer:

1.5n

Step-by-step explanation:

The distributive property can be used to simplify expressions like this (collect terms).

= n(4 -1 +.5 -2)

= n(3 +.5 -2)

= n(3.5 -2)

= n(1.5)

= 1.5n

_____

Of course, you can do the addition in any convenient way. Some like to add all the positive and negative terms, then find the difference.

= n((4 +.5) -(1 +2)) = n(4.5 -3) = 1.5n

The Solution.

The given equation is

$\begin{gathered} y=|x|+7 \\ \text{Where x=11} \end{gathered}$

Substituting 11 for x, we can get the value of y.

$\begin{gathered} y=|11|+7 \\ y=11+7 \\ y=18 \end{gathered}$

Hence, the value of y is 18.
