Answer: x=6 y=6

Step-by-step explanation:

$\displaystyle\\\left \{ {{4x-3y=6} \atop {6x-5y=6}} \right.\\$

Since the right parts of the equation are equal, therefore the left parts of the equation are also equal:

$4x-3y=6x-5y\\4x-3y+5y=6x-5y+5y\\4x+2y=6x\\4x+2y-4x=6x-4x\\2y=2x\\$

Divide both parts of the equation by 2:

$y=x\\Hence,\\4x-3x=6\\x=6\\Thus,\\x=y=6$

How to <br> Write <br> 3/9<br> in simplest form.

White raven [17]

To write it in simplest form, you must find a common factor.

In $\frac{3}{9}$ , 3 is a factor of both 3 and 9

3÷3=1 and 9÷3=3

So $\frac{3}{9} = \frac{1}{3}$

$\frac{1}{3}$ is your answer in simplest form.
