    Solve for variable

    I have an equation, and I want to solve for x.

    Here is the equation:

    (-ax + c)/b = (-dx + f)/e

    If you are able to do this, can you please explain the steps on how to do it. Thank you for your help

    Start by multiplying both sides by b, then multiplying both sides by e. This will get rid of the fractions. Then expand, collect like terms and you'll almost be done

    Re: Solve for variable

    Ok... so when you multiply that out you get "-eax + ec = -bdx + fb" right? I'm sorry, but I still do not understand what to do. Can you try explaining a little bit more (I am only in 8th grade)?

    Start by putting everything that has an x term on one side of the equation, and everything without an x term on the other side. This is called "collecting like terms".
