Answer:
Which constants can be multiplied by the equations so one variable will be eliminated when the systems are added together? 5x + 13y = 232. 12x + 7y = 218. The first equation can be multiplied by –13 and the second equation by 7 to eliminate y.

Step-by-step explanation:
multiply equation one with 12 and eqaution two with -5
then you will get
60x + 156y = 2784
-60x -35y = -1090
add these two equations to eliminate x..thus you will get only one equation containing y
