A system of equations Ax=b is usually solved in two stages. First, through a series of algebraic manipulations, the original system of equations is reduced to an upper-triangular system of the form. This can be written as Ux=y, where U is a matrix in which all subdiagonal entries are zero. That is U[i,j] = 0 if i > j, otherwise U[i, j] =.

The more experienced problem solver can do a better job of selecting equations and making proper assumptions in the first pass through Steps 3 and 4, and needs less feedback from Step 5. Step 6: After you have carried the solution as far as possible in terms of symbols, introduce numbers and units (at the same time) into the problem and ...
