Question

simplificar 2x + [-5 x - ( -2 y +{ - x + y }]​

Answer 1

Respuesta:

- 2x + y

Explicación paso a paso:

2x + [ - 5x - ( - 2y + { - x + y } ]

= 2x + [ - 5x - ( - 2y - x + y } ]

= 2x + [ - 5x - ( - 2y + y - x } ]

= 2x + [ - 5x - ( - y - x ) ]

= 2x + [ - 5x + y + x ]

= 2x + [ - 5x + x + y ]

= 2x + [ - 4x + y ]

= 2x - 4x + y

= - 2x + y
