really depends. 12x - 8y = 48 3x - 2y = 12. You can't decide, but one ordered pair is (4,0)
16
Write your answer as an ordered pair. y = -3 + 5x 3x - 8y = 24
(5,3)
3x-8y=-1 -2x+6y=1
2x+7y=29 x=37-8y
It is: x = -3 and y = -6 or as (-3, -6)
x = 8y = 6(5x8) + (3x6) = 58(5x8) - (3x6) = 22
- 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 =-3 so the lines intersect at (2, -3)
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
4y + 8y = 12y 4y - 8y = -4y 4y x 8y = 32y2 4y/8y = 1/2
