Answer 1

Respuesta:

Explicación paso a paso:

-4-(x-y)-5+(x+3y)-2-{x3y+5-(x+y-1+2+(x-y)}

-4-x+y-5+x+3y-2-[x3y+5-(x+y-1+2+x-y)]

-4-x+y-5+x+3y-2-[x3y+5-x-y+2-x+y]

-4-x+y-5+x+3y-2-x3y-5+x+y-2+x-y

=-18+7y+x

Answer 2

respuesta

 

=-18+7y+x

procedimiento

4-(x-y)-5+(x+3y)-2-{x3y+5-(x+y-1+2+(x-y)}

-4-x+y-5+x+3y-2-[x3y+5-(x+y-1+2+x-y)]

-4-x+y-5+x+3y-2-[x3y+5-x-y+2-x+y]

-4-x+y-5+x+3y-2-x3y-5+x+y-2+x-y

=-18+7y+x
