16. quita paréntesis y reduce:
A)x-(x-2)=
B)3x+(2x+3)=
C)(5x-1)-(2x+1)=
 D)(7x-4)+(1-6x)=
E)(1-3x)-(1-5x)=
F)2x-(x-3)-(2x-1)=
G)4x-(2x-1)+5x-(4x-2)=
H)(x-2)+(2x-3)-(5x-7)=

Answer 1

(A)x-(x-2)= x-x+2 = 2
B)3x+(2x+3)= 3x+2x+3 = 5x+3
C)(5x-1)-(2x+1)= 5x-1-2x-1=3x-2
D)(7x-4)+(1-6x)=7x-4+1-6x=x-3
E)(1-3x)-(1-5x)= 1-3x-1+5x=2x
F)2x-(x-3)-(2x-1)= 2x-x+3-2x+1=4-x
G)4x-(2x-1)+5x-(4x-2)=4x-2x+1+5x-4x+2=3x-1
H)(x-2)+(2x-3)-(5x-7)=x-2+2x-3-5x+7= 2-2x

Answer 2

Respuesta:

(A)x-(x-2)

   =x-x+2

   = 2

B)3x+(2x+3)

   = 3x+2x+3

   = 5x+3

C)(5x-1)-(2x+1)

   = 5x-1-2x-1

   =3x-2

D)(7x-4)+(1-6x)

   =7x-4+1-6x

   =x-3

E)(1-3x)-(1-5x)

   = 1-3x-1+5x

   =2x

F)2x-(x-3)-(2x-1)

  = 2x-x+3-2x+1

   =4-x

G)4x-(2x-1)+5x-(4x-2)

   =4x-2x+1+5x-4x+2

    =3x-1

H)(x-2)+(2x-3)-(5x-7)

   =x-2+2x-3-5x+7

    = 2-2x
