Answer 1

@iGreen

Answer 2

Simplify it.. first we add 3x to both sides:

2y > 5y + 3x + 9

Now we subtract 5y to both sides, what's 2y - 5y? @Chiko_1278

Answer 3

-3y?

Answer 4

i think

Answer 5

so its c? @iGreen

Answer 6

Yes, so we have:

-3y > 3x + 9

Now divide 3 to both sides..what's 3 / -3?

Answer 7

-1

Answer 8

Yes, so that gives us -x, and what's 9 / -3?

Answer 9

-3

Answer 10

Yep, that gives us - 3:

And our final answer is:

y < -x - 3

We switch the sign when dividing or multiplying by a negative number.
