Esperanza Moore · Answer 1

To get y alone on one side of the equation, you just move it to the other side and write a negative sign if it was positive before you moved it, or vice versa

For example: 3x+y = 7

Move 3x to the other side as a negative number

y=7-3x

Or

3x-y+7 = 0

To get y as a positive number, you would move it to the other side

3x+7 = y

All you have to do is subtract or add the numbers that are not the variable, y, on both sides to get the variable, y, on one side of the equation. Then, if there is a number in front of it, you must divide that number on both sides.
