For this case we must solve the following equation:
[tex]\frac {2} {3x} = 12[/tex]
We multiply by 3x on both sides of the equation:
[tex]2 = 12 * 3x\\2 = 36x[/tex]
We divide between 36 on both sides of the equation:
[tex]x = \frac {2} {36}[/tex]
We simplify:
[tex]x = \frac {1} {18}[/tex]
Answer:
[tex]x = \frac {1} {18}[/tex]
