    y= 3/4

    is it true?

    Yep! :) You can check this answer by plugging it in back to the equation.

    Following is the true solution

    -3+4y=0

    4y= -3

    y = 3/4

    4y= 3 actually.

    Both equations are equivalent. If the goal is to solve for y, the equation y = 3/4 is the preferred one.

    No, adding 3 to both sides gives 4y= 3, not 4y= -3.
