Step-by-step Solution

Para evaluar la expresión \( x - (-y) \), primero sustituimos los valores de \( x \) y \( y \): \[ x = -2.31 \] \[ y = 5.9 \] Sustituyendo estos valores en la expresión: \[ x - (-y) = -2.31 - (-5.9) \] Recuerda que restar un número negativo es lo mismo que sumar su valor positivo: \[ -2.31 - (-5.9) = -2.31 + 5.9 \] Ahora, realizamos la suma: \[ -2.31 + 5.9 = 3.59 \] Por lo tanto, el resultado de \( x - (-y) \) es: \[ \boxed{3.59} \]

Quick Answer

El resultado de \( x - (-y) \) es 3.59.
