I just took a test and the only problem I had issues with was this:

Solve for x. ax+b=5(x+a)

Maybe its kinda early for my brain, but could someone please walk me through the steps of how I should've solved this?

Thanks.

first let's expand the right side

this is the distributive law, review it if you don't remember it as it is extremely important

Now the name of the game is to isolate the x on one side of the equation

So lets subtract 5a from both sides

and let's subtract from both sides

and we can factor the right side

and divide through to solve for x - Sep 11th 2009, 09:15 AMNoireFox
Wow. It must be early. I knew that but I couldn't remember that for the life of me in class. So, I just guessed, and luckily I guessed that answer! :)

Thank you so much.
