OpenStudy (jsidelnikov):
The Answer is A. What you do is you write down your problem and have -1/2x+2=-x+7 Then you move the variables or the x's to one side and the numbers in this case 2 to the other. You get:-1/2x+x=7-2. Then you take and find a common denominator which is easy so you have -1/2x+2x/2=7-2/ Then you add and get 1/2x=5 then you multiply by the reciprical of 1/2 which is 2 and have 5 times 2 which is 10 so the answer is A
