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

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
