Find the Value of JG! PLEASE HELP ASAP!! I need help so bad!

Answer:
JG = 34
Step-by-step explanation:
This diagram tricked me at first but then it became visible. This question tricks you into thinking that is not an equilateral triangle when it actually is. This is because of the three lines on the JG, GW and JW lines, this means that all the lines are congruent.
If GW and JW are the same length, then:
4x - 10 = 2x + 12
Simply isolate the x's on one side by moving over the +2x making it a negative 2x and move over the -10 making it a +10:
4x - 2x = 10 + 12
2x = 22
x = 11
To prove this:
4(11) - 10 = 34
2(11) + 12 = 34
