Answer
La expresión simplificada es -a - 3.
Solution
Para resolver la expresión -2 - 4 - (a - 3), seguimos estos pasos:
1. Elimina los paréntesis: recuerda que el signo negativo delante del paréntesis se distribuye a cada término dentro del mismo.
Esto nos da: -2 - 4 - a + 3
2. Agrupa y suma los términos constantes:
-2 - 4 + 3 = -6 + 3 = -3
3. Escribe el resultado final incluyendo el término con la variable:
-a - 3
Por lo tanto, la expresión se simplifica a: -a - 3.

To simplify the expression, first, remove the parentheses by distributing the negative sign. This gives us: \( -2 - 4 - a + 3 \). Now we can combine like terms. The constants \( -2 + 3 - 4 \) equal \( -3 \). So, we have: \( -a - 3 \). Therefore, the simplified expression is \( -a - 3 \). If you plug in different values for \( a \), you can see how the expression changes! For example, if \( a = 1 \), you'd then have \( -1 - 3 = -4 \). When you substitute various values, it not only enhances understanding of the linear nature of the expression but also evokes curiosity about how changes in \( a \) create different outputs!
