# System of equations!

**Algebra**Level 5

**Which one of the following conditions must p, q and r satisfy so that the following system of linear simultaneous equations has at least one solution, such that p+q+r is not equal to 0**

**x+ 2y – 3z = p**

**2x + 6y – 11z = q**

**x – 2y + 7z = r**

**Your options-**

5p –2q – r = 0

5p + 2q + r = 0

5p + 2q – r = 0

5p – 2q + r = 0
