Algebra.. my favorite subject. In order to solve for y, you have to make x=0. So when you replace x with 0, it would look like
5(0)+4y=12..
After you do that, 5 x 0 = 0 so what you have left is 4y=12
From there it's easy. You divide both sides by 4. 4y/4 and 12/4. Y is then left alone and it is equal to 3.
Y=3

5x + 4y = 12
4y = 12 -5x
y = 1/4(12 - 5x) = 3 - 5x/4

Hey there!
Here's the answer.
5x+4y=12 --> Write the problem.
4y=12-5x --> Subtract 5x on both sides of the equation.
y=3-5/4x --> Divide 4 on both sides of the equation.
y=-5/4x+3 Use symmetric property of equality i.e. if a=b, then b=a.
So the answer is y=-5/4x+3 or y=-1.25x+3.
Hope it helps!

5x + 4y = 12
4y = 12 - 5x
y = (12 - 5x) / 4

4y=12-5x
y=(12-5x)/4
thankz for the points

y= -5/4x+3
5x+4y=12
-5x -5x
4y=12-5x
Divide by 4 on each side
4y/4=12/4-5/4x
y=3-5/4x
