Plzzzzz someone help me

Which statement is true?

The equation –3|2x + 1.2| = –1 has no solution.
The equation 3.5|6x – 2| = 3.5 has one solution.
The equation 5|–3.1x + 6.9| = –3.5 has two solutions.
The equation –0.3|3 + 8x| = 0.9 has no solution.

Answer 1

The answer is The equation 3.5|6x – 2| = 3.5 has one solution

Answer 2

The equation –0.3|3 + 8x| = 0.9 has no solution.

Explanation:

The equation –3|2x + 1.2| = –1 has no solution.

|2x + 1.2| = 1/3

this should have 2 solutions

The equation 3.5|6x – 2| = 3.5 has one solution.

|6x – 2| = 1

this should have 2 solutions

The equation 5|–3.1x + 6.9| = –3.5 has two solutions.

|–3.1x + 6.9| = –3.5/5

this has no solutions absolute values are positive

The equation –0.3|3 + 8x| = 0.9 has no solution.

|3 + 8x| = -0.9/.3

this should have no solutions since absolute values are positive
