6. 1. 1/4x + 1/2 = 7 2. 1/4 (3x + 7) = x - 2 1/2 3. 3/4 (x + 4) - 2/3 (3/4 - x) = 1/2

1.)
1/4x + 1/2 = 7
1/4x = 7 - 1/2 => samakan penyebut
1/4x = 14/2 - 1/2
1/4x = 13/2 (kalikan 4 kedua ruas)
1/4x . 4 = 13/2 . 4
x = 26

2.)
1/4(3x + 7) = x - 2 1/2
3/4x + 7/4 = x - 5/2
3/4x - x = -5/2 - 7/4 (samakan penyebut)
3/4x - 4/4x = -10/4 - 7/4
-1/4x = -17/4 (kalikan 4 kedua ruas)
-1/4x . 4 = -17/4 . 4
-x = -17
x = -17/-1
x = 17

3.)
3/4(x + 4) -2/3(3/4x - x) = 1/2
3/4x + 3 - 2/3(-1/4x) = 1/2
3/4x + 3 +2/12x = 1/2
3/4x + 2/12x = 1/2 - 3
------------------------------- x 12
9x + 2x = 6 - 36
7x = -30
x = -30/7
x = -4 2/7

semoga membantu ^^

[ setelah yang dilingkarkan itu adalah bentuk pecahan campurannya ]

20. hitunglah hasilnya perkalian pecahan berikut 1. 1 1/3 x 1/7 2. 2 1/3 x 3/4 3. 1 1/4 x 1 1/2 4. 3 5/7 x 2 1/3​

Penjelasan:

1. 4/21

2. 7/4 = 1 3/4

3. 15/8 = 1 7/8

4. 26/3 = 8 2/3

maaf banget kalo salah

semoga membantu :)
