If a, k and B are constants just asign the value they have and solve, there is no need to declare them as a syms variable.
>> syms x
>> a=1; k=1; B=1;
>> solve(((2*a)/7)*x^(3.5)-2.5*a*k*x^(2.5)+B,x)

What are the values for the constants ? Do you need to solve the system for different values of your constants?
