Question:8th Grade Algebra

posted by .

How do you get a variable term from one side of an equation onto the other side?

Can I get an example please?

  • Question:8th Grade Algebra -

    Subtract it from both sides.
    It is the same thing as changing the sign and moving it to the other side.

  • Question:8th Grade Algebra -

    Example: 3x+7=9x-15
    So your going to subtract 3x from both sides. You should end up with 7=6x-15. So now your giong to add 15 to both sides. You should get 22=6x.

    Hope that helps!! :)
