Find $a, b, c,$ and $d$ so that $$\left[\begin{array}{ll} a & b \\ c & d \end{array}\right]+\left[\begin{array}{ll} 2 & -3 \\ 0 & 1 \end{array}\right]=\left[\begin{array}{ll} 1 & -2 \\ 3 & -4 \end{array}\right]$$
Added by Michael M.
Step 1
First, we can simplify the left-hand side of the equation by adding the two matrices together: $$\left[\begin{array}{ll} a+2 & b-3 \\ c & d+1 \end{array}\right]=\left[\begin{array}{ll} 1 & -2 \\ 3 & -4 \end{array}\right]$$ Now we can see that the two matrices are Show more…
