Mathematics

I don't like these computer choice thingies. It detracts from the math.


-x - 2y = 7


5x - 6y = -3


If we want to eliminate x we multiply the first equation by 5 then add it to the second:


-5x - 10y = 35


5x - 6y + (-5x - 10y) = -3 + 35


-16y = 32


OK, that's how it's done. Reading through the choices, that's choice D.
