Get one of the solutions as Variable Value in Maxima
$begingroup$
I want to create random variables for a way more complex program to read.
Some example code is:
a:random(20);
b:random(100);
[c]:solve(a = 2 * x + b, [x]);
tex(a);
tex(b);
tex(c);
however, the last line prints x=5 instead of 5.
is it somehow possible to get the value of the solutin in maxima?

The explanation is that solve returns a list of equations such as x = 5, not just values such as 5.
Of course the values are the right-hand sides of the equations. So you can do e.g.:
[c] : map(rhs,solve(a = 2 * x + b, [x]));
