In solving {2x + 7y = -2 , 4x + 3y = -10}


by using elimination, you could eliminate the x variable in one step by multiplying the first equation by


-2. This would change it to -4x - 14y = 4


-2. This would change it to -4x -14y = -2


4. This would change it to 8x + 28y = -8


-1. This would change it to -2x - 7y = 2
