yg bisa pleaseeee jwb

ini dari buku matematika wajib kurtilas kelas 10 yah ehehe soalnya sama.

1. 2
2. 3
3. 4-7 = -3
4. jika x>0
2x-1 = 3
2x = 4
x = 2

jika x< 0
-(2x-1) = 3
-2x + 1 = 3
-2x = 2
x = -1
nilai mutlak {-1, 2}

5. jika x>0
7 - 2x = 15
-2x=8
x= -4

jika x<0
-(7-2x) = 15
-7 + 2x = 15
2x = 22
x = 11
nilai mutlak {-4, 11}

6. jika x>0
7x - 4x + 3 = 18
3x = 15
x = 5

jika x<0
-(7x - 4x + 3) = 18
-7x + 4x - 3 = 18
-3x = 21
x = -7
nilai mutlak {-7, 5}

7. jika x>0
3x + 2 = 4x - 16
-x = -18
x = 18

jika x<0
-(3x + 2) = 4x -16
-3x - 2 = 4x -16
-7x = -14
x = 2
nlai mutlak {2,18}

8. jika x>0
5-4x = 2x+13
-6x = 8
x = -8/6

jika x<0
-5+4x = 2x +13
2x = 18
x = 9
nilai mutlak {-8/6, 9}

9. (x-1 dipindahkan ke 1)
jika x>0
2x + 4 = x-1
x = -5

jika x<0
-2x -4 = x-1
-3x = 3
x= -1
nilai mutlak {-5,-1}

10. (x-4 dipindahkan ke 2)
jika x>0
3x + 2 = 2(x-4)
3x+2 = 2x-8
x = -10
jika x<0
-3x-2 = 2x - 8
-5x = -6
x = 6/5
nilai mutlak {-10, 6/5} 

kira kira begitu jalannya, kalau salah tinggal diperbaiki pake jalan yang sama

2)F=-3
3) F=4(1)-7=-3
4)2x-1 = 3
2x=3+1
x=4/2=2
5)7-2x = 15
-2X = 15-7
x = 8/-2 = -4
6)7x-4x+3= 18
3x+3=18
3x=18-3
X=15/3 =5
7)3x+2=4x-16
3x-4x = -16-2
-X = -18
x = 18
8)5-4x =2x +13
-4x-2x = 13 -5
-6x = 8
X =8/-6
= 4/-3
9)2x+4/x-1 = 1
2x+4 = 1 (x-1)
2x+4 = x-1
2x -x = -1-5
X= -6
10)3x+2/x-4 =2
3x+2 = 2 (x-4)
3x+2 =2x-8
3x-2x = -8-2
X=-10


Maaf klo slah
Btw no 1 nya ane kgk ngerti
