Step-by-step Solution
Para calcular el valor de la expresión \( a - 2b \) con \( a = 5 \) y \( b = -3 \), sustituimos los valores:
\[
a - 2b = 5 - 2(-3)
\]
Primero, calculamos \( -2(-3) \):
\[
-2(-3) = 6
\]
Ahora sustituimos este valor en la expresión:
\[
a - 2b = 5 + 6 = 11
\]
Por lo tanto, el valor de la expresión \( a - 2b \) es \( 11 \).
La respuesta correcta es: a) 11.
Quick Answer
El valor de la expresión \( a - 2b \) es 11.
