Answer 1

Respuesta:

a) 8

b)-x+2y

c)-4x+y

d) -3m-5n-6

Explicación paso a paso:

a) [(6x+7) – ( -2x + 4)] – (8x – 5)

(6x+7+2x-4)-8x+5

(8x+3)-8x+5

8x+3-8x+5

8

b) 2x + { -4x – [ - 3y + ( - x + y)]}

2x+(-4x-(-3y-x+y))

2x+(-4x-(-2y-x))

2x+(-4x+2y+x)

2x+(-3x+2y)

2x-3x+2y

-x+2y

c) (- x + y) – {5x + 2y + [- x – y – (x + y)]}

-x+y-(5x+2y+(-x-y-(x+y))

-x+y-((5x+2y+(-2x-2y))

-x+y-(5x+2y-2x-2y)

-x+y-(5x-2x)

-x+y-3x

-4x+y

d) 2m + { - [ 5n + (3m – p) + 2 – ( - m + n – p – 4)] – ( m + n)}

2m+(-(5n+3m-p+2+m-n+p+4)-m-n

2m+(-(4n+4m+6) -m-n)

2m+(-4n-4m-6-m-n)

2m+(-5n-5m-6)

2m-5n-5m-6

-3m-5n-6
