If you wanted to eliminate the y variable by adding the two equations in the following system, what could be your first step? x − y = 6 4x − 3y = 12 Add the two equations together Multiply the first equation by −4 Multiply the first equation by 3 Multiply the first equation by −3
It would be the last answer: Multiply the first equation by -3
I would multiply the first equation by -3 because then the -y would turn to 3y which will eliminate the -3y of the second equation when the two equations are added.
