$$tq=0$$

This means that or t or q or both are zero

$$0*1=0 , 1*0=0, 0*0=0$$

The second equation says you that $$rq=1$$. Now, $$r =1$$ and $$q=\frac{1}{2}$$ for being rq=1. Or vice-versa but this does not matter. What we care is that q must be equal to a certain number.

As it turns out, in the first equation $$tq= 0$$, q = a number. As such, t must be equal to zero for being $$tq=0$$

Hope this helps.

Regards
