The two equations/lines are $parallel$. No solution.
We use the addition method below: We add the 2 equations: $16x-36y=70$ $4x-9y=17$ Multiply both sides of the second equation by $-4$ to cancel $x$. $+16x-36y=70$ $\underline{-16x+36y=-68}$ $0=2$ This is a false statement. No solution. So the two equations/lines are parallel.
