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

You 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.

ok

would 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 y-intercept out of the equation

careful - if you multiply by 4 when you add them you actually get -8y. You'll want to multiply the second equation by -4 actually.
