# Euclidean Geometry #5

**Geometry**Level pending

In \(\mathbb{R}^3\) consider the line r whose equations are:

**r \(\equiv\) {x - 2y - 2z = 1, x + 5y - z = 0}**

and the plane \(\pi\) whose equation is **\(\pi \equiv 2x + y +mz = n\)**. Find m, n and submit your answer as m + n, knowing that r is contained in \(\pi\)
