Solving a set of linear equations interactively

Dear All!

I intend to solve a set of linear equations using coefficients obtained from run time. Matlab displays:

solution = 
    x: [1x1 sym]
    y: [1x1 sym]

symbolic expressions I cannot convert to readable numbers even with double() function. Pls help

    % Code solves a general linear sim equation in two variables
    % Accept coefficient of x in line one
    a11 = input('Enter coefficient of x eqn one:')
    a12 = input('Enter coefficient of y in eqn one: ')
    c1  = input('Enter the constant term  in eqn one:')
    eqn_one = sym( 'a11*x + a12*y + c1');
    a21 = input('Enter coefficient of x in eqn two:')
    a22 = input('Enter coefficient of y in eqn two:')
    c2  = input('Enter the constant term in eqn two:')
    eqn_two  = sym( 'a21*x + a22*y + c2');
    solution = solve(eqn_one, eqn_two)
