# Windows 7: Anybody good at algebra?

 04 Oct 2010 #1 Boomstick777 Windows 7 x64 Enterprise 94 posts Anybody good at algebra? Does anybody know how you would make 'k' the subject of the equation? See the pic attached. Any help would be appreciated.. http://i51.tinypic.com/2mnj3uf.jpg Attached Thumbnails My System Specs

Remember what you do to one side of the = sign you do to the other side. hint....multiply both sides by k then divide each side by "a" k=????????/ My System Specs

Remember what you do to one side of the = sign you do to the other side. hint....multiply both sides by k then divide each side by "a" k=????????/ Thanks for your reply. k = b^2/a? I just don't get the method of this I need an example so can do the rest... Does the sqr'b' stay the same even though it swapped sides? I thought it would become b^2? My System Specs

 04 Oct 2010 #8 The Howling Wolves Windows 7 Home Premium 64bit 9,642 posts California Find out what you each is asking for then do whatever it takes to get it alone on one side. Then do the same to the other side.. In the first one you multiplied both sides by k then divided by "a" to both sides to get k=b^2/a Do that to the rest of them.... My System Specs

Does the (Square root of b) stay as sqr(b) or change to b^2 (b,squared)? Im confused becasuce thought there would be more work to do, it looks like the 'k' has just been swapped out for the 'a'..

 04 Oct 2010 #10 BugMeister Windows10 Pro - 64Bit vs.10547 3,834 posts UK the answer to Q.a is the easiest, since it just involves shifting the three expressions around Q.b is slightly more complex since it involves balancing the equation by doing some arithmetic - remember that what you do to one side of the equation, you must also do to the other.. so - for example, taking 2 from the right side means that you also have to do the same to the left.. you are not being asked to simplify the equations - just to rearrange them..
