Tolong bantu jawab
1. 1 per 2 (x-4)=6
2. 2 per 3 (5x+2)=2(x+2)
3. 2x-1 per 3 + 6x+4 per 2 = 4x+3
4. 2y+4 per 4 - 4y-1 per 3 =1

Answer 1

1. 1/2 (x-4)=6
1/2x - 2=6
1/2x=8
x= 16

2. 2/3 (5x+2)=2(x+2)
10/3x + 4/3 = 2x+4
10/3x -2x = 4 - 4/3
4/3x = 8/3
x = 8x3/3x4
x= 24/12
x= 2

3. 2x- 1/3 + 6x+4/2 = 4x+3
8x + 10/6 = 4x+3
8x - 4x = 3 - 10/6
4x = 8/6
x = 8/6x4
x= 8/24
x= 1/3

4. 2y+4/4 - 4y-1/3 =1
-2y +2/3 =1
-2y = 1/3
y = -1/6
