Answer:

y = 6x

x = 6x

Explanation:

To solve this system of equations, we can first rewrite the equations in standard form, where the left-hand side of the equation is equal to zero. To do this, we can subtract the constants 3 and 12 from both sides of the equations, respectively. This gives us the equations:

Y = -2x

8x + 4y = 0

To solve this system, we can use the elimination method, which involves multiplying one or both equations by constants to eliminate one of the variables. Let's multiply the first equation by 4 and the second equation by -2:

4Y = -8x

-16x - 8y = 0

Now we can add the two equations together to eliminate the x-variable:

-16x - 8y = 0

4Y = -8x

Adding these two equations gives us:

-8y + 4Y = -8x - (-16x)

-8y + 4Y = -24x

Next, we can simplify the left-hand side of the equation by combining like terms:

(-8y + 4Y) = -24x

-4y = -24x

Finally, we can divide both sides of the equation by -4 to solve for the y-variable:

y = 6x

Thus, the solution to this system of equations is x = 6x.
