In this equation, your eventual goal is to isolate y. Let's see how to do this:

 \(y-1-2y=y+1-3y\) Simplify both sides of the equation by combining like terms. In this case, the linear terms can be combined to simplify things \(-y-1=-2y+1\) Add y to both sides of the equation. Doing this will have a y that will cancel on the left hand side. \(-1=-y+1\) Subtract 1 from both sides \(-2=-y\) Divide by -1 to get rid of the negative sign on the y. \(2=y\)

If you are ever pondering about whether or not this answer is correct, plug the answer you got into your equation and see if the statement is true. :

 \(y-1-2y=y+1-3y\) Replace all instances of a y with a 2 \(2-1-2*2=2+1-3*2\) Simplify and see if the statement is true \(2-1-4=2+1-6\) \(1-4=3-6\) \(-3=-3\) Indeed, this is a true statement.

Therefore, \(y=2\) is the correct and only correct solution for the given equation
