Hey i would like to find the solutions for this system assuming that my unknows are X Y and Z
solve doesnt work
syms X Y Z
eq1=sqrt((a1-X)^2+(b1-Y)^2+(c1-Z)^2) == D1+R1;
eq2=sqrt((a2-X)^2+(b2-Y)^2+(c2-Z)^2) == D2+R2;
eq3=sqrt((a3-X)^2+(b3-Y)^2+(c3-Z)^2) == D3+R3;
eq4=sqrt((a4-X)^2+(b4-Y)^2+(c4-Z)^2) == D4+R4;
TY

Hi Steewz,
From the question, I understand that you want to solve the given set of quadratic equations for X,Y,Z. Since not specified in the question, I am assuming the other variables as constants which can be specified later(or you can assign them to be syms variable too).
sol = solve([eq1, eq2, eq3], [X, Y, Z]);
For accessing the results you may use:
sol.X;
sol.Y;
sol.Z;

Hi,
Writing the above code as:
sol = solve([eq1, eq2, eq3,eq4], [X, Y, Z]);
should solve the problem too, If it's giving some unexpected behavior it'd be helpful if you could share the values of constant as well.
