The Line PQ is cut half equally by point T. MEANING PT=TQ!!! So first, write out the equation.
PT = TQ
20?5x+3=7x-9
21?4x-6=3x+4
22?7x-24=6x-2
The question asks you to find the value of PT, but you’ll have to find the value of x first.
x=6
x=10
x=22
And then just just plug in x in just the PT equation.
5(6)+3= 33
4(10)-6= 34
7(22)-24= 130
and there you have it
20?=33
21?=34
22?=130
