其實依條問題原本係一條constrain optimization既問題(你見有 Lambda), 所以基本上有冇steps都唔係差好遠, 但係如果有steps既話, 咁就更加好喇(我想溫番依part, 會考後已經幾年未掂過algebra喇!)

s = 2147/5843 = 0.3674482286496663
b = 2613/5843 = 0.4472017799075817
c = 1083/5843 = 0.185349991442752
λ = 26491/29215000 = 0.0009067602259113469

You can then use Gaussian Elimi. to solve for the num. values.http://mathworld.wolfram.com/GaussianElimination.htmlOr, you can solve the system using Excel.Excellent success with your studies!
