Jim, Carla And Sammy Are Members Of The Same Family. Carla Is 5 Years Older Than Jim. Sammy Is 6 Years Older Than Carla. The Sum Of Their Three Ages Is 31 Years. How Old Is Each One Them?​

Jawaban: #1:

Jawaban:

Jimmy = 5 years old

Carla = 10 years old

Sammy = 16 years old

Penjelasan:

Jim = j

Carla = c

Sammy = s

c = 5 + j

s = 6 + c // s = 6 + (5 + j)

j + c + s = 31

Metode Substitusi

• Mencari umur Jim

j + c + s = 31

j + (5 + j) + (6 + 5 + j) = 31

3j + 16 = 31

3j = 31 - 16

3j = 15

j = 5

• Mencari umur Carla

j + c + s = 31

5 + c + (6 + c) = 31

2c + 11 = 31

2c = 31 - 11

2c = 20

c = 10

• Mencari umur Sammy

j + c + s = 31

5 + 10 + s = 31

15 + s = 31

s = 31 - 15

s = 16

maaf kalo salah

semoga membantu, ya.. ^^
