Answer:
#9) x = 11, y = 3
Step-by-step explanation:
So #9...
because l&m are parallel...
[tex]9x + 25 = 13x - 19[/tex]
because m is a straight line...
[tex](13x - 19) + (17y + 5) = 180[/tex]
solve for x in the first one and plug into the second equation to solve for y...
[tex]4x = 44 \\ x = 11[/tex]
[tex]13(11) - 19 + 5 + 17y = 180 \\ 17y = 180 - 129 \\ y = 3[/tex]
