Explanation:

Step1: Apply additive length property

$ST + TU = SU$

Step2: Substitute given expressions

$(x + 5) + 2x = 8$

Step3: Combine like terms

$3x + 5 = 8$

Step4: Isolate the variable term

$3x = 8 - 5$
$3x = 3$

Step5: Solve for x

$x = \frac{3}{3} = 1$

Step6: Calculate TU value

$TU = 2x = 2 \times 1$

Answer:

$2$
