Answer 3

i didn't get it :@

see if this helps your case

Answer 5

Answer 6

xy= -3/2
so y = ?

Answer 7

-3/2x

Answer 8

thats what the question demands ma'am! :3

Answer 9

i mean how did you know that i can use any operation?

Answer 10

you just have find relation between x and y, these are 2 simple eqns, eqns don't get simpler than this. Its just normal to know that there'll many ways to find a relation between x and y

Answer 11

if i use division let say , then i am getting y=-24x
but since this does not lie in the answers, then i should use another operation right?

Answer 12

thats right
we already know the values of x and y
x= 1/4 and y = -6

there are endless ways to write y in terms of x !

what other time saving thing you could have done is checking from the options
put value of x in that option, if it comes out to be y, then thats the required answer, otherwise try next..

Answer 13

that is what i did and i got A as the answer, but i wanted a solid solution and now i have that as well :)

Answer 14
