Question

5. 1/y - 1/2 = 1/3

7. 6/y + 3/y = 15/4

harus jawab yang benar
sama pake caranya

Answer 1

Jawaban:

Sistem persamaan linear satu variabel

Untuk nomor 5

Untuk nomor 7

Answer 2

1/y - 1/2 = ⅓

2-y/2y = ⅓

3 ( 2 - y ) = 2y

6 - 3y = 2y

6 = 2y + 3y

6 = 5y

y = 6/5

y = 1 1/5

_____________________

6/y + 3/y = 15/4

6+3/y = 15/4

9/y = 15/4

15(y) = 9(4)

15y = 36

y = 36/15

y = 12/5

y = 2 2/5
