Question

Selesaikan persamaan berikut.
1. 9p + 9 = 8p + 4
2. 6p + 7 = 5p - 14
3. 7p - 14 = 6p - 8
4. -4x = 12
5. -3/4x = -3/8
6. 1/4x = 2/3
7. 8x -8 = -24
8. 4y + 5 = 37

Answer 1

1. 9p + 9 = 8p + 4
9p-8p = 4-9
p = -5
2. 6p + 7 = 5p - 14
6p-5p = -14-7
p = -21
3. 7p-14 = 6p-8
7p-6p = -8 + 14
p = 6

Answer 2

1. 9p+9=8p+4
9p-8p=4-9
p = -5
2.6p+7= 5p-14
6p-5p= -14-7
p=-21
3.7p-14=6p-8
7p-6p=-8+14
p= 6
4.-4x=12
x= 12/4
x=3
5.-3/4x=-3/8
x= -3/8 * 4/3
x= -3/6 jika disederhanakan => -1/2
6. 1/4x = 2/3
x= 2/3 *-4/1
x= -8/3 disederhanakan menjadi => -2 2/3
7.8x-8=-24
8x= -24+8
8x=-16
x=-2
8. 4y+5=37
4y=37-5
4y=32
y=8
