Question

Hola.
Alguien me puede ayudar a despejar estás ecuaciones :³

"2x + 5= -6x -8", "2x-(4x + 4) = 5x + 3", "x(3+3)=4x + 12" y "2(x + 3) -4 = 3(x -5) + 7x"

Answer 1

Respuesta:

$2x + 5 = - 6x - 8 \\ 2x + 6x = - 8 - 5 \\ 8x = - 13 \\ x = \frac{ - 13}{8}$

$2x - (4x + 4) = 5x + 3 \\ 2x - 4x - 4 = 5x + 3 \\ 2x - 4 = 5x + 3 \\ - 4 - 7 = 5x - 2x \\ - 11= 3x \\ x = \frac{ - 11}{3}$

$x(3 + 3) = 4x + 12 \\ x(6) = 4x + 12 \\ 6x = 4x + 12 \\ 6x - 4x = 12 \\ 2x = 12 \\ x = 6$

$2(x + 3) - 4 = 3(x - 5) + 7x \\ 2x + 6 - 4 = 3x - 15 + 7x \\ 2x + 2 = 10x - 15 \\ 15 + 2 = 10x - 2x \\ 17 = 12x \\ x = \frac{17}{12}$
