You need to isolate the variable. To do this, you put all terms with x on one side of the equation, and you put all the terms without x on the other side.

3x+=+x%2F2+%2B+10

3x+-+x%2F2+=+10

Now, you need to solve for x. In this case, you can factor it out, then divide both sides by the remaining constant:
x%283+-+1%2F2%29+=+10

x%285%2F2%29+=+10

x+=+4
