Question

Tolong jawab linear pecahan ini ya soalnya penting plzz
1. x/3 - 14/6 = 5x + 7
2. 3x + 2/3 = 1/2 (x + 1)
3. 3y + 1/4 = 4y + 1/2
4. x-3 x + 1
----------- = 3 - ---------
2 4

5. 2/5x -1 = 6/10
6 4x + 2 2x + 1 6x + 3
--------------- - -------------- = -------------
3 2 4

Answer 1

Tolong jawab linear pecahan ini ya soalnya penting plzz
1. x/3 - 14/6 = 5x + 7
x/3-5x=7+14/6 kedua ruas kalikan 6
maka
2x-30x=42+14
-28x=56
x=-56/28 bagi 7
x=-8/4

2. 3x + 2/3 = 1/2 (x + 1)
3x+2/3 = 1/2x + 1/2
3x-1/2x=1/2-2/3
5/2x= 1/6
x=1/6 / (5/2)
x=1/6 x 2/5
= 2/30
= 1/15

3. 3y + 1/4 = 4y + 1/2 kedua ruas kalikan 4
12y+1=16y+2
12-16y=2-1
-4y=1
y=-1/4


selebihnya kerjakan sendiri

Answer 2

5) 2/5x - 1 = 6/10
2/5x = 1 6/10
2/5x = 16/10
x = 16/10 : 2/5
x = 16/10 × 5/2
x = 8/2
x = 4
( no.4 dan no.6 gk jelas , maaf ya )
