Answer:
3 should be added to the first equation in order to eliminate y
Step-by-step explanation:
when multiplying the first equation by 3 we get (7x-5y+2=0)×3 = 21x-15y+6=0
Now adding the newly obtained equation to the second equation we get
21x - 15y + 6 = 0
+ 2x + 15y + 3 = 0
23x + 00 + 9 = 0
Hence Y is eliminated
