Title: Re: Below is a magic square where the sum of the three numbers in each row, column a Post by: BearPro on Feb 26, 2012 you have to find values of unknown variables
w ,x,y,z yoi can make four equations and then you can deduce the value of these unknown variables. like, for the first equation, you write sum of elements in column 1 equals sum of elements in column 2 or whatever rows or columns you want. you can compute values of unknown variables by making equations by making use of the fact that sum is constant whethee it ia taken along a row or a colimn or diagonally. |
