Question

-{x - 2y +y-[3x +5xy +6y-(x-y)+8]}

Answer 1

-{x - 2y +y-[3x +5xy +6y-(x-y)+8]}-{x- 2y + y -[3x + 5xy +6y -x + y +8]}=-{x - 2y + y -[2x +5xy +7y +8]}=
-{x - 2y + y - 2x - 5xy - 7y - 8}=
-x + 2y - y + 2x + 5xy + 7y + 8 =
 x + 8y + 5xy + 8 =
x + 5xy + 8 + 8y =
x(5y+1) + 8(y+1)

Answer 2

Resposta:

Explicação passo a passo:-{x - 2y +y-[3x +5xy +6y-(x-y)+8]}-{x- 2y + y -[3x + 5xy +6y -x + y +8]}=-{x - 2y + y -[2x +5xy +7y +8]}=

-{x - 2y + y - 2x - 5xy - 7y - 8}=

-x + 2y - y + 2x + 5xy + 7y + 8 =

x + 8y + 5xy + 8 =

x + 5xy + 8 + 8y =

x(5y+1) + 8(y+1)
