Use the matrices Mista H has below to find x if 2B - x = A
-2 -4 -8 (next row = -8 -10 -16)
3 6 9 (next row = 12 15 18)
-3 -6 -9 (next row = -12 -15 -18)
2 4 8 (next row = 8 10 16)

- 9x - 9 = 0 and solve, you rewrite -9x as ___________, then get solutions of _________
-5x - 4x; x = 5/4, -9
5x + 4x; x = -5/4, 9
-12x + 3x; x = 3, -3/4
12x - 3x; x = -3, 3/4
