The point of intersection of the lines $\to r \times \to a = \to b \times \to a$ and $\to r \times \to b = \to a \times \to b$ is

\to r = \to a + λ (\to b \times \to c)

\to r = \to b + μ (\to c \times \to a)

\to a =^i +^j

\to b = 2^i +^j

\to r \times \to a = \to b \times \to a & \to r \times \to b = \to a \times \to b

\to a =^i +^j

\to b = 2^i -^k

\to r \times \to a = \to b \times \to a

\to r \times \to b = \to a \times \to b
