Hi,
to convert to math problem:
I.  Assign 'x' (variable)
II.  Write as you read ***
III. Solve for x
A number twice that number{{{highlight_green(x)}}}, and one-third of that number{{{highlight_green(x)}}} are added. 
the result is 20
*** {{{ 2x + x/3 = 20}}}     Solve for x  (Multiplying thru by 3 so as all denominators = 1
    6x + x = 60
      7x = 60
       x = 60/7          Or 8 <sup>4</sup>&frasl;<sub>7</sub>  
CHECKING our answer***
 {{{120/7 + 20/7 = 140/7 = 20}}}
