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
