You can put this solution on YOUR website! To solve for Y, we have to get Y by itself on one side of our equal sign. So, for 3x + 4y + 12 = 0, first we can subtract 12 from both sides of our equal sign:
3x + 4y + 12 - 12 = 0 - 12, giving us
3x + 4y = -12
Next, we can subtract 3x from both sides of our equal sign: 3x - 3x + 4y = -12 - 3x, giving us
4y = -12 - 3x
Finally, we can get the y by itself by dividing both sides by 4:
This leaves us with
The right side of our equal sign can be simplified, because we know that
is the same thing as
Reducing this down results in our final answer
