Answer:

answer is attached in the image below

Answer 2

17. -6b + 20 = -16
-6b+20-20= -16-20
-6b = -36
b = 6
18. -4m + 2 = 14
-4m + 2 -2 = 14 - 2
-4m = 12
m=-3
19. -9c-4=-4
-9c-4+4=-4+4
-9c=0
c=0

20. 2y- (-10) = 18
2y+10=18
2y+10-10=18-10
2y=8
y=4

21. 1/2g+2=6
0.5g+2=6
0.5g+2-2=6-2
0.5g=4
g = 8

22. 3r-25=5
3r-25+25=5+25
3r = 30
r =10

23. 2/3s-(-4)=8
2/3s+4=8
2/3s+4-4=8-4
2/3s=4
s=6

24. 4/5a+(-5)=0
4/5a-5=0
4/5a-5+5=0+5
4/5a = 5
a= 25/4 aka 6.25

25. -2/7w -6 = -4
-2w/7=2
(-7/2)(-2a/7)=(7/2)•2
a=-7
