Question

5×-8=8×+1 por favor ayuden 2(×-10)=30 2(×-4) =20

Answer 1

Respuesta:

$5x - 8 = 8x + 1 \\ - 1 - 8 = 8x - 5x \\ - 9 = 3x \\ x = \frac{ - 9}{3} = - 3 \\ 5 \times ( - 3) - 8 = 8 \times ( - 3) + 1 \\ - 15 - 8 = - 24 + 1 \\ - 23 = - 23$

Explicación paso a paso:

$2(x - 10) = 30 \\ 2x - 20 = 30 \\ 2x = 30 + 20 \\ 2x = 50 \\ x = \frac{50}{2} = 25 \\ 2(25 - 10) = 2 \times 15 = 30 \\ 2(x - 4) = 20 \\ 2x - 8 = 20 \\ 2x = 20 + 8 \\ 2x = 28 \\ x = \frac{28}{2} = 14 \\ 2(14 - 4) = 2 \times 10 = 20$

espero te sirva
