    Solving Linear Equations

    I am trying to find the values of t and v of 2 equations. The equations are

     distance = 25t-100v

     distance = 100v-35(600-t)

    where t = time and v = velocity at the time t

    I am trying to solve with matlab and so far this is what i have got

    clear all
    syms t v
    eqn1=25*t-100*v;
    eqn2=100*v-35*(600-t);
    [X,Y]=solve(eqn1,eqn2)

    The result that i get is t = 350 & v = 175/2. I am expecting the result for t to be about 650 and v to be about 25.

    Can anyone give me an idea of what i am doing wrong and guide me in the right path.

    Thanks

    Matlab is solving (correctly) the equations

    25t-100v=0,
    100v-35(600-t)=0.

    What equations do you want it to solve ?
    Does distance have a (numerical) value ?
