Question

Find CJ please :)))))

Answer 1

Well, first you should try setting them equal to each other, as they're equal.

5+3x=2x+11
-5 -2x -2x -5
------------------
x = 6

From there, just plug it in, so

CJ = 5 + 3(6)
CJ = 5 + 18
CJ = 23

Answer 2

Here you go...
5+3x=2x+11
-5 -5
3x=2x+6
-2x -2x
x=6

P.S.: hope I helped :)
