(-11, 5)

1) Given the lines describe by 6y - x= 41 and 6y -5x = 85

2) Let's find out the intersection point, solving this Linear system:

6y - x= 41 x( -1) Multiply by -1 to eliminate y term

6y -5x = 85

-6y +x = -41

6y -5x = 85

---------------------

-4x =44

4x=-44

x=-11

2.2) Now let's plug into the 1st equation x= -11

6y -(-11) = 41

6y +11 = 41

6y = 41-11

6y = 30

y= 5

3) Hence, the point of intersection is (-11, 5)
