Solve by elimination. Rewrite the first as 9x + 12y = 17 and the second as -3x - 4y = 31. Multiply the second equation by 3:
-9x - 12y = 93.
Add this to the first equation:
(9x + 12y) + (-9x - 12y) = 17 + 93 → 0 = 110,
a contradiction. Therefore the system is inconsistent and has no solution (the two lines are parallel).
-9x - 12y = 93.
