ME AJUDEM PFVR
Simplifique a expressão algébrica: 2/3x + 1/3y + 4/5x + 2/5y + 10 *
a) 2/5x + 7/9y + 10.
b) 22/15x + 11/15y + 10.
c) 22 /15x + 12/15y +10.
d) 4/7x + 5/6y + 10.
e) 7/15x + 2/15y + 20.

vou dar a melhor resposta:)

Answer 1

2/3x + 4/5x = 10/15x + 12/15x = 22/15x
1/3y + 2/5y = 5/15y + 6/15y = 11/15y

MMC do 3 e 5 é o 15

22/15x + 11/15y + 10
