2y - 6x = -8
You have two unknowns and only one equation. In the absence of any other information, this equation cannot be solved.
What can be done is to make each unknown the subject of the equation.
2y = 6x - 8
y = 3x - 4
6x = 2y + 8
3x = y + 4
x = (y + 4)/3

5+y+2y? = 5+3y?
Put in this form. Y =mX + c4X - 2Y = - 1- 2Y = - 4X - 1Y = 2X +1/2=============Linear, as in a line.
10-y=2y+3 10-3=2y+y 7=3y 7/3=y
(2y+1)(y−5)
2x + 2y isn't an equation and doesn't ask any question, so there's nothing to solve,and nothing that needs an answer.If (2x + 2y) were equal to something, and there was another equation to go along withthat one, then it would be possible to figure out what 'x' and 'y' must be.
