Find the value of the variable and VW if V is between U and W.

UV=2,VW= 3x, UW=29
UV = r, VW = 6r, UW =42
UV = 4p - 3, VW = 5p, UW =15
UV = 3c+29, VW = -2c-4, UW = -4c

Need a site to explain how to do these.
Teacher not clear on explaining.

UV + VW = UW

8) UV + VW = UW
2 +3x = 29
3x = 27
x = 3
VW = 3x = 9

9) UV + VW = UW
r + 6r = 42
7r = 42
r = 6
VW = 6r = 36

10) UV + VW = UW
4p-3 + 5p = 15
9p = 18
p = 2
VW = 5p = 10

11) UV + VW = UW
3c+29 + -2c-4 = -4c
c - 25 = -4c
5c = 25
c = 5
VW = -2c-4 = -10-4 = -16
