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...

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}]
