solution Adding the given matrices, we get [ begin{array}{l} quad(X+n)+(X-eta)=left[begin{array}{ll} 5 & 2 0 & 9 end{array}right]+left[begin{array}{ll} 3 & 6 0 & -1 end{array}right] Rightarrow 2 X=left[begin{array}{ll} 5+3 & 2+6 0+0 & 9+(-1) end{array}right] Rightarrow 2 X=left[begin{array}{ll} 8 & 8 0 & 8 end{array}right] Rightarrow X=frac{1}{2} cdotleft[begin{array}{ll} 8 & 8 0 & 8 end{array}right]=left[begin{array}{ll} 4 & 4 0 & 4 end{array}right] end{array} ] On subtracting the given matrices, we get
