What do 6, 9 and 12 have in common? 3.
-6y / 3 = -2y
+9x / 3 = +3x
+12z / 3 = +4z
Since they share 3, write 3 outside the brackets, and your solutions inside the brackets:
3(3x-2y+12z)

6z+28=12z+10 6z-12z=10-28 addition property of equality. -6z=-18 simplification z=3 multiplication property of equality.
6z + 28 = 12z + 10 18 = 6z 3 = z
-3z+17+12z = 11 9z = -6 z = -2/3

-99 = 12z - 3(6)zSimplifying the expression, we have:-99 = 12z - 18z = -6zDivide by -6:z = 16.5Or, if you meant 3 6 as the number, we have:-99 = 12z - 36zSimplify:-99 = -24zDivide by -24:z = 4.125
