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.
