In the product F = qB (vectors), take q = 2 (neglecting the units of charge, q) and v = 2.0 i + 4.0 j + 6.0 k and F = 4.0 i + (-20 j) + 12 k . What then is B in unit-vector notation if Bx=By ?

Don't you mean the vector cross product
F = q V x B ?

You need to write an equation for the three components of B (with Bx = By) by rewriting the above equation for the individual components. Then solve for the Bz and Bx=By components
