Particle in a magnetic field - x,y,z components

[Luxe]

Homework Statement

A particle with charge 2.8 C moves through a uniform magnetic field. At one instant the velocity of the particle is (1.4 i + 1.2 j + 0.48 k) m/s and the magnetic force on the particle is (11.9 i - 14.1 j + 1.57 k) N. The x and y components of the magnetic field are equal. What are (a) the x-component, (b) the y-component, and (c) the z-component of the magnetic field?

Homework Equations

F=q(v X B)

The Attempt at a Solution

I have tried this twice and cannot figure out this solutions. Can someone please point be in the right direction?

If the vector B is B=B_xi+B_yj+B_zk

What is q(vxB) equal to? (Write this in the vector form)

Since they gave you what F is, and you just calculated q(vxB) (which is F), equate components.
