Complete Solutions 

Question 1: Solve for x: 6x = 42 

Approach: 
Step 1: Divide both sides by 6. x = 7 
Note: Okay, the professor was explaining this in class, but I had to ask an extra question for more help (I went to tutoring after class) 

Exercise 2: Solve for x: 5x = 45 
Answer: 
Step 1: Divide both sides by 5. 
x = 9 
Note: This reminds me of the homework problem from Set 4, specifically question 4. 
Good work! 

Problem 3: Solve for x: 5x = 45 
Solution: 
Step 1: Divide both sides by 5. 
x = 9 
Note: The trick was correctly applying the logarithm properties. 

4.: Solve the system of equations: 5x + 4y + 3z = -4 2x + 3y + 5z = 3 4x + 2y + 4z = -10 Work: 
Step 1: Use the elimination or substitution method. 
(Solution would involve matrix operations or step-by-step elimination, which would be unique for each problem) 
Step 2: The solution is a set of (x, y, z) values.
