Rearrange the equations in the form of:

x+3y = 17z

3*(3x-y = z)

Multply the second equation by 3:

x+3y = 17z

9x-3y = 3z

Add them together to eliminate y:

10x = 20z

Divide both sides by 10:

x = 2z

Substitute the value of x into the original equations to find the value of y:

Therefore the point of intersection is: (2z, 5z)
