Answer:

PT=57

Step-by-step explanation:

If PT=7x+8 and TQ=9x-6 qnd we have that T is the midpoint of PQ.

Since T is the midpoint of PQ, [tex]PT=TQ[/tex]

We substitute into the equation to get:

[tex]7x+8=9x-6[/tex]

Group the similar terms to get:

[tex]8+6=9x-7x[/tex]

We simplify now to get:

[tex]14=2x[/tex]

Divide through by 2 to get:

[tex]x=7[/tex]

PT=7*7+8=49+8=57
