Sederhanakan!!!
(a+b-c)-(⅓a – 1/5b + ¼c)-(-1⅓a + 1¼b – 4/5c)
Jawaban Terkonfirmasi
= a+b+c-1/3a+1/5b-1/4C+1 1/3a -1 1/4b + 4/5c
= (a – 1/3a + 1 1/3a) + (b+1/5b-1 1/4b) + (c-1/4c+4/5c)
=(1-1/3+ 1 1/3) a + (1+1/5 – 1 1/4) b + (1-1/4+4/5) c
= 6/3a – 1/20b + 31/20c
= 2a – 1/20b + 1 11/20c
Maaf kalau salah.
(a+b-c)-(⅓a – 1/5b + ¼c)-(-1⅓a + 1¼b – 4/5c) = 40a – b – 9c
