solving non linear equation

f1=@(x1,x2) [acos((x1-4.8)/x1)*x1*x1 - (x1-4.8)*sqrt(9.6*x1-(4.8)^2)]*x2 -15000;

f2= @(x1,x2) [acos((x1-9.9)/x1)*x1*x1 - (x1-9.9)*sqrt(19.8*x1-(9.9)^2)]*x2 -48000;

please help me to provide script code to solve this

thank you so much

syms x1 x2 
eqn(1) =  (acos((x1-4.8)/x1)*x1*x1 - (x1-4.8)*sqrt(9.6*x1-(4.8)^2))*x2 -15000 == 0;
eqn(2)=  (acos((x1-9.9)/x1)*x1*x1 - (x1-9.9)*sqrt(19.8*x1-(9.9)^2))*x2 -48000 == 0;

s = vpasolve(eqn,[x1 x2]) ;
s.x1

ans = 

s.x2

ans =

i will try in matlab to see result

thanks

Edited the answer showing results..

[satyajit kumar]

can there be multiple solution ? because value does not satify to my application

if yes then hoe other solution points be extracted?
