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 :)

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".

This is also called me being an idiot. Thank you for the help :)
