Respuesta:
A) la x es igual a -5
Respuesta paso a paso:
2x + 8 = -2
2x = -2 - 8
2x = -10
x = -10:2
x = -5
Explicación paso a paso:
[tex]5x - 12 = x + 4 \\ 5x - x = 4 + 12 \\ 4x = 16 \\ x = \frac{16}{4} = 4 \\ 5 \times 4 - 12 = 4 + 4 \\ 20 - 12 = 8 \\ 8 = 8[/tex]
[tex]2x + 8 = - 2 \\ 2x = - 2 - 8 \\ 2x = - 10 \\ x = \frac{ - 10}{5} = - 5 \\ 2 \times ( - 5) + 8 = - 10 + 8 = - 2[/tex]
espero te sirva
