7. Explain why the equation 6|x| + 25 = 15 has no solution.

When one solves, they arrive at a step where |x| is equal to a fraction that may not be represented as an integer. Since | x| must be an integer, there is no solution.

When one solves, they arrive at a step where x is equal to a negative number. Since x can never be negative inside of the absolute value bars, there is no solution.

When one solves, they arrive at a step where |x| is equal to a negative number. Since | x| can never be negative, there is no solution.

The statement is false. There is a solution.

Step-by-step explanation:

6|x| + 25 = 15

Subtract 25 from each side

6|x| + 25-25 = 15-25

6|x|  = -10

Divide by 6

6|x| /6 = -10/6

|x|  = -5/3

There is no solution because the absolute value must be greater than or equal to zero.  This equation has it negative.

Hi,

Actually there is no solution.

Because the statement is given that it's false.
