Is there a way to make the following work and solve the following set of symbolic equations for the same variable and save the output in an array?
syms x a
eqns = [a==x+2, a==5*x];
xvalues = vpasolve( subs(eqns,a,[1,2]) , [x,x] );

I do not believe any solution exists to those equations, especially after the subs call.

Becasue you hava two equations with two unknowns (x & a), so you will not need to substitute any value for a:
syms x a
eqns = [a==x+2 a==5*x]
[xsol asol]=solve(eqns,[x a])

It accidentally happens to have two equations of two variables in my question, but how about that?
syms x a
eqns = [a==5*x];
xvalues = vpasolve( subs(eqns,a,[1,2,3,4]) , repel(x,4) );
