G)7y-2y
H)5 . (y-1)
pf se puder me ajudar

Answer 1

A) 2x+3x = 5x

B) 8y -5y = 3y

C) 8a -3a +4a =
      \     /
       5a +4a = 9a

D) 5x +6x -x =
       \    /
       11x -x = 10x

E) 8a +7a = 15a

F) 5x +x +9x = 15a

G) 7y-2y = 5y

H)5 . (y-1) =
    5.y +5.(-1) =
    5y -5 =
    5y = 5
      y = 5/5
      y = 1
  

Answer 2

(A) 2x+3x=5x

(B) 8y-5y=3y

(C) 8a-3a+4a=5a+4a=9a

(D) 5x+6x-x=11x-x=10x

(E) 8a+7a=15a

(F) 5x+x+9x=6x+9x=15x

(G)7y-2y=5y

(H) 5.(y-1)= 5y-5y=0y
