It seems the image you uploaded is a bit blurry. From what I can make out, the text contains some mathematical expressions written in Spanish. It seems to involve sums and fractions. Specifically, I can make out:

1. "Un cuarto de la suma de 2p y 11" – which refers to "A quarter of the sum of 2p and 11".
2. "Suma de 2x" – which refers to "Sum of 2x".
3. An expression involving a fraction, possibly something like "(2/3)x + 5".
4. A subtraction operation involving "v", probably in "y (11 - v)".

Could you clarify any specific part you would like to focus on or explain further?
