    Hello,

    8x-(x+5)=13+2(x-2)
    Expand both sides of the equation:
    8x-x-5=13+2x-4
    You'll get now:
    7x-5=2x+9
    Gather the variables on the LHS of the equation and the constants on the RHS of the equation:
    5x=14
    Divide by the coefficient of x:
    x=14/5

    Hello,

    it's me again:

    I'm quite confused by this problem which I did actually three times:
    For jim1174
    for maxmac97
    and for you: bounine.

    Either your complete class is registered to this forum and every one has just the same problem or you are a triplet in one body and you don't talk to yourself.

    Please don't be disappointed but I won't do any problems for you anymore.

    Greetings
