To find x and tv, substitute the known values into the given equations and solve for x and tv. The value of x is 5.5, and tv is 4.5.
To find the value of x and tv, we can use the equations provided. From the given information, we have:
ru = 8
us = 14
tv = x - 1
vs = 17.5
We can start by substituting the known values into the equation ru + us = tv + vs:
8 + 14 = (x - 1) + 17.5
Simplifying the equation:
22 = x + 16.5
Subtracting 16.5 from both sides:
x = 5.5
Now we can substitute the value of x into the equation tv = x - 1:
tv = 5.5 - 1 = 4.5
