6 - x = 2(x - 6)
the first step, following PEMDAS, is to distribute the 2 to the inside of your parentheses:
6 - x = 2x - 12 ... subtract 2x
6 - 3x = -12 ... subtract 6
-3x = -18 ... divide by -3
x = 6 is the answer
Cot = Cos/Sin
Cos = 12/13
Sin = 5/13
Therefore, 12/3 divided by 5/13 equals 12/5
Answer is 1.
