How to solve unknown number of equations

Let say I do not know the number of equation to be formed.
Let say I need n, the number of equations,
where n may vary from solving each time.
for i=1:n
syms vi vi+1 v-1
eqn i = (vi+1)^2+(vi-1)^2==20
end
So I get my n number of equation. However that won't work in matlab. Kindly suggest how to do the same.

Hi, I understand you are trying to create number of equations. You can do this using syms. Here is a sample code.
clc;
clear all;
n=input("Enter Number of Equations to be formed: ");
syms v [1,n]
for i=1:n
eqn(i) = (v(i)+1)^2+(v(i)-1)^2==20;
disp(eqn(i));
end

Here is a sample code for it.
clc;
clear all;
% Forming Equation
n=2;
syms v [1,n]
for i=1:n
eq(i) = (v(i)+1)^2+(v(i)-1)^2==20;
disp(eq(i));
end
% Solving Equation
[v1_sol,v2_sol]= solve(eq,v);
disp(v1_sol);
disp(v2_sol);
