120 because 60x2=120 and 10x12=120
When i multiplied i ended up getting 1 7/8
They are similar because 4/2 = 8/4
Answer = D; 1, -5
i’m not sure how to explain it, sorry!
Multiplying the first equation and multiplying it by -8/3 (to get rid of the x), we get -8y/9+7y= -64+8=-56. Therefore, -56/(-8/9+7)=y and 8- 7(-56/(-8/9+7))=x by plugging it into the second equation
