Solve for X in the equation, where A=[−546−202] and B=[01−3402]4B=−2X−2A Step 1 The matrix equation is given as 4B=−2X−2A. The first step is to solve the equation for X just as in linear equations. Add 2A to both sides of the equation and then divide both sides of the equation by -2 to solve for X. (−2∨−2)B−A=X Step 2 x=(−1)[−5−5446−2−2002]+(−20]−2][01−3402] Step 3 Perform the scalar multiplication before the addition of matrices. Remember you can multiply a matrix by a scalar c by multiplying each entry in the matrix by c. Multiply each entry in A by (−1) and each entry in B by (−2). x=[5−4−620−2]+[◻◻◻00◻◻◻]
