Answer:

x = 6 and y = 3

Explanation:

Your equation: -2x-4y=-12

__________________________________________________

First, we'll solve for x.

You need to divide -2x on both sides.

**We'll exclude/forget the -4y since we're not dealing with it right now.

-2x = -12

x = 6

When dividing with negatives, if both of the numbers are negatives they shall cancel and become positive.

-12 divided by -2 is 6 positive.

Therefore, x = 6

_______________________________________________________

Next, we'll solve for y

The same thing as last, we'll exclude our -2x since we're not dealing with it anymore.

-4y = -12

-12 divided by -4 is a positive answer since the two negatives cancel out.

-12/ -4 = 3

Therefore, y = 3

________________________________________________________

The proper vocabulary of the "x" and the "y" are x-intercept and y-intercept.

We just solved for both.
