Reduce the equation of line `x-y+2z=5a d n3x+y+z=6` in symmetrical form. Or Find the line of intersection of planes `x-y+2z=5a n d3x+y+z=6.`

Explanation

Let `a`, b and c be the direction ratios of the required line. Since the required line lies in both the given planes, we must have


`a-b+2 c=0`


and


`3 a+b+c=0`
