Let A and B be any two matrices of same order m × n, then their sum A ± B = [aij ± bij]m × n where A = [aij]m × n and B = [bij]m × n
Calculation:
Given: 2A - B + X = O, where O is the null matrix, \(A = \left[ {\begin{array}{*{20}{c}} 3&1\\ 0&2 \end{array}} \right]\;and\;B = \left[ {\begin{array}{*{20}{c}} { - \;2}&1\\ 0&3 \end{array}} \right]\)
