p=4i−2j+8k\mathbf{p} = 4\mathbf{i} - 2\mathbf{j} + 8\mathbf{k}p=4i−2j+8k and q=xi+yj+zk\mathbf{q} = x\mathbf{i} + y\mathbf{j} + z\mathbf{k}q=xi+yj+zk
Given that the resultant force of p\mathbf{p}p and q\mathbf{q}q is 7i+5j−2k7\mathbf{i} + 5\mathbf{j} - 2\mathbf{k}7i+5j−2k, find the values of xxx, y y\,y and zzz.
