Question

a+3/2 - 4/5 + 4-3a/3 =0 Me ajudem!!!

Answer 1

Oi Kayla


(a + 3)/2 - 4/5 + (4 - 3a)/3 = 0

mmc(2,3,5) = 30

15*(a + 3) - 24 + 10*(4 - 3a) = 0

15a + 45 - 24 + 40 - 30a = 0

30a - 15a = 45 + 40 - 24 

15a = 61  

a = 61/15 

Answer 2

(a + 3)/2 - 4/5 + (4 - 3a)/3 = 0

mmc(2,3,5) = 30

15*(a + 3) - 24 + 10*(4 - 3a) = 0

15a + 45 - 24 + 40 - 30a = 0

30a - 15a = 45 + 40 - 24

15a = 61

a = 61/15 :
