Answer 2

Solution to the Equations:

Let's solve the given equations one by one:

1. |x| = 7: - The absolute value of x is equal to 7. - This means that x can be either 7 or -7.

2. |x| = -5: - The absolute value of x cannot be negative. - Therefore, there is no solution to this equation.

3. |5x + 1| = 4: - The absolute value of 5x + 1 is equal to 4. - This gives us two possible equations: - 5x + 1 = 4, which gives x = 3/5. - -(5x + 1) = 4, which gives x = -5/5 = -1.

4. |10x - 5| = -6: - The absolute value of 10x - 5 cannot be negative. - Therefore, there is no solution to this equation.

5. |2x + 11| = 0: - The absolute value of 2x + 11 is equal to 0. - This means that 2x + 11 must be equal to 0. - Solving for x, we get x = -11/2.

To summarize, the solutions to the given equations are: - x = 7 or -7 (from |x| = 7) - x = 3/5 or -1 (from |5x + 1| = 4) - x = -11/2 (from |2x + 11| = 0)

Please note that there is no solution to the equation |x| = -5 and |10x - 5| = -6.

I hope this helps! Let me know if you have any further questions.
