Wow, my friend and I are both on our laptops in the same room surfing different sections of Yahoo Answers. I'm home to the boxing section and just answered your question there, and he sends me the link to this question asking if I know X and I realize- I just got done answering your question in the boxing section and he's seeing a question you asked here without knowing I answered your boxing question. That's like a 1/500,000,000 chance. Calculate that sh1t.
x = 16
The first three steps are to isolate the x. (This is essential in solving algebra problems.) The final step is necessary to make the x positive.
1. subtract sixes from both sides. The equation should now look like:
-2 (10-x) = 12
2. divide both sides by negative two:
10-x = -6
3. subtract ten from both sides:
-x = -16
4. multiply both sides by negative one:
-1 ( -x ) = -1 ( -16)
double negatives make a positive
x = 16
Everything done to one side must be done to the other.
subtract 6 from both sides:
-2(10-x)=12
divide both sides by -2
(10-x)=-6
subtract 10 from both sides
-x=-16
divide both sides by -1
x=16
