Question 951196: I'm studying for an assessment test and this is not a good start. I'm now feeling anxiety that I will fail both answering and completing the test on-time; I don't normally do well on timed tests. Up to this moment I thought I had a successful career now I'm thinking the results will measure my ability to manage; all this after a 30 year career. I tend to over think questions and situations. The test that I need to take is for Numeric Reasoning. It's a timed test; 20 minutes for 18 questions. I appreciate any tips.
I'm having trouble understanding how the answer was derived for the following question.
If Andrew's department receives 6 new computers, they will have 1/2 as many as if they had received 24 new computers.
Q: How many computers does Andrew's department have prior to receiving any new one's?
Thanks, BVF

Let x be the number of computers that the office had prior to receiving any new ones.
x+6=(x+24)/2
2x+12=x+24
x=12

Thanks Ed I appreciate your response.
That's how I set up the equation with the exception of adding x to the right side. My set up included the following:
x+6=1/2*24
Q: why is x added to the right side?
.
Because the problem states that you must add 24 to the original number of computers and the original number is x
