    Rearrange the equation ao that A appears on the left hand side of the equation on its own. B=3A+2C+8

    I am really confused, i understand that we you do to one side of the equation you do to the other. But how do you know what to add or subtract, is it the 8 or the 2C or...

    thanks in advance

    You should have posted your question separately, not as an answer to someone else. Use the command
    "Post a new Question" at the top of a Jiskha page.

    First switch sides (since they want A on the left), and then subtract 2C + 8 from both sides.

    3A = B - 2C -8

    Next, divide both sides by 3.

    A = B/3 -2C/3 - 8/3
