Answer
a) \( 85 - 6 + b = 79 + b \)
b) \( 42b - 8 + 8 = 42b \)
c) \( 743 + 10 - 10 = 743 \)
Solution
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) \( 743 + 10 - 10 = 743 \)

Explain 
Simplify this solution The Deep Dive
To solve \( 85 - 6 + b = 79 + b \). So, you just need to find the value of \( b \) to complete the equation! Next up, for \( 42b - 8 + 8 \), the -8 and +8 cancel each other out, simplifying down to just \( 42b \). So you can focus on solving or further manipulating that. Lastly, for \( 743 + 10 - 10 \), the +10 and -10 also cancel each other out, simplifying to \( 743 \). So, the answer remains \( 743 \). Keep practicing these, and they'll become second nature!
