\begin{array}{rcrcrcrcrcr}
a & + & 2b & + & 3c & + & 4d & + & 5e & = & 47, \\
2a & + & 3b & + & 4c & + & 5d & + & e & = & -15, \\
3a & + & 4b & + & 5c & + & d & + & 2e & = & -18, \\
4a & + & 5b & + & c & + & 2d & + & 3e & = & 3, \\
5a & + & b & + & 2c & + & 3d & + & 4e & = & 14.
\end{array}
a+2b+3c+4d+5e=47,2a+3b+4c+5d+e=−15,3a+4b+5c+d+2e=−18,4a+5b+c+2d+3e=3,5a+b+2c+3d+4e=14.
