(A) 7x + 4x =___________

(B) 9x – 4x + x = ________

(C) 5y + 8 +6y + 12 = _____

(D) 5x + 5 + 3x -3 =_______

(E) 12 x + 14 – 7x = ______

E URGENTE ​

Answer 1

Oie, Td Bom?!

A)

= 7x + 4x

= (7 + 4)x

= 11x

B)

= 9x - 4x + x

= 9x - 4x + 1x

= (9 - 4 + 1)x

= 6x

C)

= 5y + 8 + 6y + 12

= (5 + 6)y + 8 + 12

= 11y + 8 + 12

= 11y + 20

D)

= 5x + 5 + 3x - 3

= (5 + 3)x + 5 - 3

= 8x + 5 - 3

= 8x + 2

E)

= 12x + 14 - 7x

= (12 - 7)x + 14

= 5x + 14
