1.3w+6=4w 2.a+18=7a 3.8c=5c+21 4.11d+10=6d 5.2e=4e-16 6.7v=2v-20 7.4n-6=10n 8.2y+27=5y 9.8h=6h-14 10.18-2g=4g. Can You Help?

Here is the solution for each:
 1.   3w+6=4w
4w-3w=6
w=6 is the answer
 
2.   a+18=7a
7a-a=18
6a=18
a=18/6=3 is the answer
 
3.  8c=5c+21
8c-5c=21
3c=21
c=21/3=7 is the answer
 
 
4.  11d+10=6d
11d-6d=10
5d=10
d=10/5=2 is the answer
 
5.  2e=4e-16
4e-2e=16
2e=16
e=16/2
e=8 is the answer
 
 
6.  7v=2v-20
7v-2v=-20
5v=-20
v=-20/5= -4 is the answer
 
 
7.  4n-6=10n
10n-4n=-6
6n=-6
n=-1 is the answer
 
8.  2y+27=5y
5y-2y=27
3y=27
y=27/3
y=9 is the answer
 
 
9.  8h=6h-14
8h-6h=-14
2h=-14
h=-7 is the answer
 
 
10.  18-2g=4g
4g+2g=18
6g=18
g=18/6
g=3 is the answer
