Ok this is how you do it...you have to get the numbers with the variable on the same side so 7.45x becomes -7.45x and they cancel eachother out..then you subtract the -7.45x from 9.47x..you get 2.02x..so now this is what the problem looks like..-8.81=5.29+2.02x..now you have to get the nuumbers without the variable son the sma eside so 5.29 becomes -5.29 and you subtract that from -8.81..now the problem looks liek this -14.1=2.02x...now you divide 2.02 by 2.02..they cancel ecaother out and you divide -14.1 by 2.02 and you get -6.98...there's your naswer! I hope you understand now! good luck! x0x

Aight mate. Here's how you do that. I'm not going to solve it for you, I'll just tell you how.
Subtract 7.45x from both sides. That leaves -8.81 = 5.29 + (9.47 - 7.45) x Let's just call (9.47 - 7.45)x as y. So now -8.81 = 5.29 + y Subtract 5.29 from both sides, and you wind up with -8.81 - 5.29 = y Do the actual mathy part yourself you lazy bum! Just kidding... hope I helped!

You need to try to get x onto one side. So here are the basic steps starting with the whole problem
7.45x - 8.81 = 5.29 + 9.47x
Add 8.81 on left side to cancel it out, and then add it to the other side.
7.45x = 14.1 + 9.47x
Now, add 7.45x and 9.47 x
16.92x = 14.1
Divide each side by 16.92
x = ? What do you get?
