1. combine what you know:  3x + 5x    &   19-29

so you have 8x-10 = 180
 
Move the 10 to the other side....  so you have 8x = 190  
to solve for x....  divide 190 by 8.

I want my son to be quick with basic addition and subtraction through the number 12.  When I was in school we used to have timed tests and the winner got a special treat.  It sure motivated everyone to do better...  I would like to do that with my little guy too!

Anything like this I find khan academy really good or just google the problem and you can generally find it on youtube. Or try your library they are really quite good or a bookstore, you might be surprised.
