Let's simplify each expression by following the order of operations:
20 + 3(x-15)20 + 3(x) - 3(15)20 + 3x - 453x - 25
16 - 4(2+a)16 - 8 - 4a8 - 4a
-35 - 12(b-3)-35 - 12b + 36-12b + 1
-18 + (4-x)-18 + 4 - x-14 - x
42 - 6(7+y)42 - 42 - 6y-6y
29 - 3(t-8)29 - 3t + 24-3t + 53
Therefore, the simplified expressions are:
