Sure, let's simplify each of the given expressions:

### a) $$ 85 - 6 + b $$

**Simplification:**
$$
85 - 6 + b = 79 + b
$$

### b) $$ 42b - 8 + 8 $$

**Simplification:**
$$
42b - 8 + 8 = 42b
$$
*Explanation:* The $$-8$$ and $$+8$$ cancel each other out.

### c) $$ 743 + 10 - 10 $$

**Simplification:**
$$
743 + 10 - 10 = 743
$$
*Explanation:* The $$+10$$ and $$-10$$ cancel each other out.

**Final Answers:**

a) $$ 85 - 6 + b = 79 + b $$

b) $$ 42b - 8 + 8 = 42b $$

c) $$ 743 + 10 - 10 = 743 $$
a) $$ 85 - 6 + b = 79 + b $$ b) $$ 42b - 8 + 8 = 42b $$ c) $$ 743 + 10 - 10 = 743 $$

a) \( 85-6+b= \) b \( 42 b-8+8= \) c \( 743+10-10= \)
