Help please I need help I can't do this alone

Answer:
CT = 13x-1
but if you need the answer
CT = 38
Step-by-step explanation:
if CJ is equivalent to JT, and
CJ = 8x-5
and
JT = 5x+4
so, 8x-5=5x+4
if you simplify it, 8x = 5x+9
use simple algebra to find that x = 3
and because CT is 13x-1, 13(3)-1 = 38
