Answer:
t = (u -v)/2
Step-by-step explanation:
Observe what is done to t:
- multiplied by 2
- v added to the product
Undo these operations, starting with the last one and working up the list.
[tex]u = v+2t \qquad\text{given}\\\\u-v=2t \qquad\text{undo addition by subtracting $v$}\\\\\dfrac{u-v}{2}=t \qquad\text{undo multiplication by dividing by 2}\\\\\boxed{t=\dfrac{u-v}{2}}[/tex]
