Current Attempt in Progress

In the cross $($or vector$)$ product vec$(F)=$qvec$(v)$vec$(B)$ we know that

$q=1$

vec$(F)=-21$hat$(i)+-9\mathrm{.}0$hat$(j)+-12$hat$(k)$

vec$(v)=-3\mathrm{.}0$hat$(i)+3\mathrm{.}0$hat$(j)+3\mathrm{.}0$hat$(k)$

vec$(B)=B_x$hat$(i)+B_y$hat$(j)+B_z$hat$(k)$

What then is vec$(B)$ in unit$-$vector notation if $B_x=B_y?$
