If you wanted to eliminate the y variable by adding the two equations in the following system, what could be your first step?
2x − 4y = 6
3x − y = 12
Add the two equations together
Multiply the first equation by −4
Multiply the second equation by −4
Multiply the second equation by 4

Best ResponseYou've already chosen the best response.1so going off of wat u said i need to add them first or i need to get rid of the Y's first

Best ResponseYou've already chosen the best response.1You need to multiply one equation by a constant, and then add them. You want to make it so that the constant you mutiply by cancels out the y value when you add them.

Best ResponseYou've already chosen the best response.1would it be D because mulitply 4 * 1 its going to be 4 and when you and 4 and 4 together it cancels each other out leaving the yintercept out of the equation

Best ResponseYou've already chosen the best response.1careful  if you multiply by 4 when you add them you actually get 8y. You'll want to multiply the second equation by 4 actually.
