TERMS ON BOTH SIDES OF AN EQUATION:
and *** this one I tried, but kept getting the wrong answer etc..
here is the problem***

Any help would be greatly appreciated, as I am studying for a test in Pre-algebra/algebra, and need to attain a score of 55+ in Pre-algebra, and a score of 30+ in algebra. This test is on Saturday, (28th March), and I have been studying, religiously, but then..somewhere along the way, I become hopelessly lost, and end up with answerrs that are so-far out in left field, that I am not even sure I am in the same class etc....I should mention, that I am a returning adult...and not fresh out of High-School. My last algebra class was twenty-five+ years ago etc.....
Thank-you for your time, and any helpful suggestions..other than do not enter school would be greatly appreciated!!!! (the above joke was a lame attempt at keeping/finding humour in this stressful aspiration!!!)
Thanx~ John
