QUESTION 1 You ARE required to show work for this question. Solve for the 2 \times 2 matrix $X$ in the equation $A + 2X = B$ where $A = \begin{bmatrix} 2 & 1 \ -1 & 4 \end{bmatrix}$ and $B = \begin{bmatrix} 1 & 2 \ 3 & 4 \end{bmatrix}$ Don't worry about inputting a matrix in its proper form. Just enter the values in each row in the blanks below. Row 1 of matrix $X$ Row 2 of matrix $X$
