The lines intersect at (3, 5)
- 2(3X - 8Y = - 18)3(2X + 5Y = 19)- 6X + 16Y = 366X + 15Y = 57----------------------------add31Y = 93Y = 3========now, find X; second equation will do2X + 5(3) = 192X + 15 = 192X = 4X = 2==========both check and are consistent(2, 3)-----------------ordered pair
x = 2 and y =1 so the lines intersect at (2, 1)
-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
Y=-1
