Answer 5

cross multiply what though?

Answer 6

@KendrickLamar2014

Answer 16

3 * y = 3y

Answer 17

So we have:

6x + 3y = 2 * 2x

What's 2 * 2x?

Answer 18

4x

Answer 19

what's next?

Answer 20

@iGreen

Answer 21

We have:

6x + 3y = 4x

Subtract 6x to both sides, what's 4x - 6x?

Answer 22

2x

Answer 23

@iGreen

Answer 24

Actually that's negative, which gives us:

3y = -2x

Divide -2 to both sides:

\(-\dfrac{3}{2}y = x\)

Divide 'y' to both sides:

\(-\dfrac{3}{2} = \dfrac{x}{y}\)

So -3/2 is your answer.
