Answer

La respuesta simplificada es: \(-11x + m - 8\).

Solution

1. Reescribimos la primera parte: \[ -6x + 4m - 2 + 2x = (-6x + 2x) + 4m - 2 = -4x + 4m - 2 \] 2. Reescribimos la segunda parte: \[ 7x + 5 + 3m + 1 = 7x + 3m + (5+1) = 7x + 3m + 6 \] 3. Aplicamos la resta: \[ \begin{aligned} &[-4x + 4m - 2] - [7x + 3m + 6] \\ &= -4x + 4m - 2 - 7x - 3m - 6 \end{aligned} \] 4. Combinamos términos semejantes: - Términos con \(x\): \(-4x - 7x = -11x\) - Términos con \(m\): \(4m - 3m = m\) - Términos constantes: \(-2 - 6 = -8\) Así, obtenemos: \[ -11x + m - 8 \]

Simplify this solution

The Deep Dive

Primero, simplificamos las expresiones dentro de los corchetes: En el primer corchete: \[ -6x + 4m - 2 + 2x = (-6x + 2x) + 4m - 2 = -4x + 4m - 2 \] En el segundo corchete: \[ 7x + 5 + 3m + 1 = 7x + 3m + (5 + 1) = 7x + 3m + 6 \] Ahora restamos el segundo corchete del primero: \[ [-4x + 4m - 2] - [7x + 3m + 6] = -4x + 4m - 2 - 7x - 3m - 6 \] Ahora combinamos los términos semejantes: \[ (-4x - 7x) + (4m - 3m) + (-2 - 6) = -11x + 1m - 8 \] Así que la expresión resultante es: \[ -11x + m - 8 \]
