4x-y=2 2x+9y=-12 unsure how to solve
2 answers:
Simple, use the process of elimination to figure this out: 4x-y=2 2x+9y=-12 Convert these, to be able to find either x or y. 2(4x-y=2) 8x-2y=4 multiply by 2. then 4(2x+9y=-12) 8x+36y=-48 Which makes them 8x-2y=4 - 8x+36y=-48 -38y=52 This simplified makes it y= -26/19. Then plug y back into the original equation 4x-y=2 4x-(-26/19)=2 Making it x= 3/19. Thus your Point of Intersection is at (3/19, -26/19)

The final result is:
x = 3/19 and
y = -26/19 .
