Dear All,

Given the enclosed code - see below.
Please could someone help me setup the code to Solve / Reduce for these 2
missing values only required 

  {SQ1 -> 5292, 
    XX -> 0.25}

(I don't want multiple results.) I want positive numbers & NOT Complex..


Many thanks for your help & attention, really appreciated. Please see below.

Best regards,
Lea...

Clear[SQ1]
Clear[XX]
Solve[{(1/6)*((SQ1*196)*2)^3 - 
         (1/6)*((((2.75 + XX)*((3.75 + XX)*21^2))*100)*2)^3 == 
       1.2902698935932682*^18, (1/6)*((SQ1*100)*2)^3 - 
         (1/6)*((((2.75 + XX)*((3.75 + XX)*21^2))*36)*2)^3 == 
       1.883856772422697*^17}, {SQ1, XX}]
