ayuda es que no entiendo encerio​

Answer 1

Respuesta:

30 240 = 280 × 108

280 = -8 × -31,25

108 = 54 × 2

-8 = -4 × 2

-31,25 = -15,625 × 2

54 = 27 × 2

2 = -2 × -1

Explicación paso a paso:

30 240 = 108x

30 240/108 = x

x = 280

280 = -8x

280/-8 = x

x = -31,25

108 = 2x

108/2 = x

x = 54

2 = -2x

x = -1

54 = 27 × 2

-31,25 = -15,625 × 2
