數学問題!!!!!!!

1. (h+12)÷3=9
h + 12 = 27
h = 15

2. 4分之1(p-2)+6=15
1/4 ( p -2 ) = 9
p = 2

3. 2分之1+3分之q=16
q / 3 = 15又2分之1
q = 5又6分之1

4. 5分之3r-2分之1-2=6
5分之3r = 8 又2分之1
3r = 42又2分之1
r = 14又6分之1

5. 4s-8+2=7
4s = 13
s = 3.25

6. 4-t+2=7
4 - t = 5
t = -1

7. 6(u+5)+2(u+5)=80
8( u + 5 ) = 80
u + 5 = 10
u = 5

8. 2w-4分之w=42
1又4分之3w = 42
w = 24

9. 2分之4-x+5分之--1-2=0

I don't know ....... 5分之 what

10. 2分之4-x+5分之x-1-2=0
I don't know what your mean............ 係 5分之x or 5分之x-1
