Question

solve using the elimination method -7x -6y = -42; 5x - 2y = -14

Answer 1

Make something the same, I chose the x terms.
\[(5)*(-7x-6y=-42)\]\[(7)*(5x-2y=-14)\]
Add
\[-35x-30y=-210\]\[35x-14y=-98\]
Wallah
\[-44y=-308\]\[y=7\]

Answer 2

Ok thanks, I got y =7 but I have to find out what x equals. but I get -7x equals 0. so what does x equal?

Answer 3

Well, what do you have to multiply -7 by to get 0?
