Value of \[x\]is \[c\]such that \[x\ \square \ d=a\].

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