Tolong jawab yah besok di kumpulin plss

1. 2x= 6x+12
2x-6x=12
-4x=12
x= -3
2. 3(n-6)=2(n-5)
3n-18=2n-10
3n-2n=-10+18
n=8
3. 6p+7=5p-14
6p-5p=-14-7
p=-21
4. 7p-14=6p-8
7p-6p=-8+14
p=6
5. 3x-2=x+8
3x-x=8+2
2x=6
x=3
6. 3x+2=6x-1
3x-6x=-1-2
-3x=-3
x=1
7. 9x+5=2x+7
9x-2x=7-5
7x=2
x=2/7
8. 3(2p-2)=5p+3
6p-6=5p+3
6p-5p=3+6
p=9
