Hello
In the output the values give this result. I want to get the values:
syms X1 X2 X3 X4
eq=[X1^2+X2^2==1949.947, (X1*X3)+(X2*X4)==-28.338, eq3=(X3*X1)+(X4*X2)==-28.338, eq4=X3^2=X4^2-81.892]
[x1,x2,x3,x4]=solve([eq],[X1,X2,X3,X4])
x1 =
Empty sym: 0-by-1
x2 =
Empty sym: 0-by-1
x3 =
Empty sym: 0-by-1
x4 =
Empty sym: 0-by-1
Thank you for helping me

Your second and third equations are the same. There would not be a unique solution .

syms X1 X2 X3 X4
eq1 = X1^2+X2^2==1949.947 ;
eq2 = (X1*X3)+(X2*X4)==-28.338;
eq3 = (X3*X1)+(X4*X2)==-28.338;
eq4 = X3^2==X4^2-81.892 ;
eqs = [eq1, eq2, eq3, eq4] ;
s=solve(eqs,[X1,X2,X3,X4]) ;
s.X1
s.X2
