Recall that the three manipulations we can perform on the equations in a system.
Replace an equation in the system with a constant multiple of that equation
Replace an equation in the system with the sum or difference of the two equations
Replace an equation with the sum of that equation and a multiple of the other
For each combination of matrices, write out the justification that allows you to write the new matrix.
