Value of \[x\]is \[b\], such that \[x\ \square \ d=e\].

Find\[x\ \square \ d=e\]as, Now, find column under \[d\]of the second table, and then find\[e\]under that column to get the corresponding row to get the value of \[x\]. Thus, value of \[x\]is \[b\]. Hence, the value of \[x\]is \[b\]such that \[x\ \square \ d=e\].
