x = 20

Step-by-step explanation:

From the strip diagram attached in the picture,

Addition of the expressions on the two strips in orange color and yellow color gives 320.

So, by adding the two expressions given on orange and yellow strips,

4x + 12x = 320

16x = 320

x = 20

Therefore, answer will be x = 20.
