I will be using a practice problem with different endpoints, and I challenge you to solve this one using a similar strategy. The points I will be using is
(1, 3) as T and (5, 4) as the midpoint

Alright - we know that the equation for the midpoint of a line segment is

( ( x_(1) + x_(2) )/(2) , ( y_(1) + y_(2) )/(2) )
Next, we plug the x values in - since the midpoint's x value is 5 and one endpoint's x value is 1, we have

(1+x_2)/(2) =5 .
Next, we multiply both sides by 2, resulting in 1+x₂=10. Lastly, we subtract 1 from both sides, meaning that x₂, or the x value of the other endpoint, is 9. For the y values, we use a similar process -

(3+y_2)/(2) =4 .
since 3 is the y value of one endpoint and 4 is the y value of the midpoint. Multiplying both sides by 2, we get 3+y₂=8. Subtracting 3 from both sides, we get y₂=5 and our coordinates for the other endpoint to be (9, 5).

Good luck, and feel free to ask any questions as necessary!
