    first multiply the scalar 2 by the matrix 2 -8 -4 2 to get 2*2 -8*2 -4*2 2*2 4 -16 -8 4 so we now have this |dw:1366763853215:dw|

    your next step is to subtract this matrix you just got from both sides |dw:1366763918364:dw|

    doing that will cancel out these matrices on the left side |dw:1366763994359:dw| since they add or subtract to the zero matrix
