Answer 2

To solve the equations |2x + 13| = 0 and |11x - 4| = -5, let's work on each equation separately.

1. |2x + 13| = 0:

The absolute value of any real number is always non-negative. Therefore, the absolute value can only be equal to zero when the expression inside the absolute value is zero.

So, in this case:

2x + 13 = 0

Subtract 13 from both sides:

2x = -13

Now, divide both sides by 2 to solve for x:

x = -13/2

2. |11x - 4| = -5:

The absolute value of any real number is always non-negative. Therefore, the absolute value can never be equal to a negative number. This equation has no solution because there are no real values of x that will make |11x - 4| equal to -5.

So, the first equation has a solution:

x = -13/2

And the second equation has no real solutions.
