ANSWER:
12

EXPLANATION:
set PT equal to TQ, so 3x+3= 6x-6
add six to both sides so 3x+9 = 6x
subtract 3x from both sides so 9=3x
divide both sides by 3 so 3=x
x=3
now just plug 3 in for x 3(3)+3
9+3
12

Answer:

12

Step-by-step explanation:

the equation to find x is PT=TQ

(3x+3)=(6x-6)

calculate and you'll get x=3

put 3 into PT equation

3(3)+3=12
