Expanding each expression:
(10x+2)-6(5x-11) = 10x + 2 - 30x + 66= -20x + 68
(5x-7)+10(x-2)+3(12-5x) = 5x - 7 + 10x - 20 + 36 - 15x= 0 - 1x + 9= -x + 9
Therefore, the simplified expressions are:

= -20x + 68
(5x-7)+10(x-2)+3(12-5x) = 5x - 7 + 10x - 20 + 36 - 15x
= 0 - 1x + 9
= -x + 9
Therefore, the simplified expressions are:
-20x + 68-x + 9
