Answer:

x=36

Step-by-step explanation:

So, lets go over what we know:

16 is equal to 4/9ths of x.

As a equation, this looks like:

$16 = \frac{4}{9}x$

We can begin to solve for x by multiplying both sides by the denominator, 9, which gets us:

$16*9 = 4x$

$144 = 4x$

Then we can divide by the coefficent of x, which is 4, to get our answer:

$\frac{144}{4} = x$

$36=x$

This is our answer! Hope this helps! :3

Answer:

$\large\boxed{y=\dfrac{2}{3}x-4}$

Step-by-step explanation:

$2x-3y=12\qquad\text{subtract}\ 2x\ \text{from both sides}\\\\2x-2x-3y=12-2x\\\\-3y=12-2x\qquad\text{divide both sides by (-3)}\\\\\dfrac{-3y}{-3}=\dfrac{12}{-3}+\dfrac{-2x}{-3}\\\\y=-4+\dfrac{2}{3}x$
