5x + 3 ­­­­­­­/ 2(x + 4 ) = 3/5

(a) x = 7/17

(b) x = 7/19

(c) x = 9/17

(d) x = 9/19

5x + 3 ­­­­­­­/ 2(x + 4 ) = 3/5

5x+3 = 3/5 . (2x+8)

5x=6x/5 + 24/5 - 15/5

25/5x - 6x/5 = 9/5

19/5x = 9/5

x = 9/5 . 5/19

x = 9/19

Resposta D

caraduradepau

5x+3/2=3(x+4)/5

5(5x+3)=2*3(x+4)

25x+15=6x+24

25x-6x=24-15

19x=9

x=9/19

anonymous

5x+3/2x+8=3/5

25x+15=6x+24

19x=9

x=9/19

Letra (d) x = 9/19

vamos la

(5x+3)/(2x+8)= 3/5 multiplica cruzado okkk

5(5x+3)= 3(2x+8)

25x+15= 6x+24

19x= 9

x= 9/19 letra D okkkkk
