Answer 3

Calculating the Expression |7x-5|-4•|5-7x|

To calculate the expression |7x-5|-4•|5-7x|, we can follow these steps:

1. Calculate the value of |7x-5|: - The absolute value of a number is the non-negative value of the number, regardless of its sign. For example, |3| = 3 and |-3| = 3. - In this case, we have |7x-5|. - The value of |7x-5| will depend on the value of 7x-5. If 7x-5 is positive, then |7x-5| = 7x-5. If 7x-5 is negative, then |7x-5| = -(7x-5). - We can then proceed to calculate the value of 7x-5 and -(7x-5) separately.

2. Calculate the value of |5-7x|: - Similarly, we have |5-7x|. - The value of |5-7x| will depend on the value of 5-7x. If 5-7x is positive, then |5-7x| = 5-7x. If 5-7x is negative, then |5-7x| = -(5-7x). - We can then proceed to calculate the value of 5-7x and -(5-7x) separately.

3. Substitute the calculated values into the expression: - Once we have the values of |7x-5| and |5-7x|, we can substitute these values into the expression |7x-5|-4•|5-7x| and perform the necessary operations to obtain the final result.

Let's proceed with the calculations based on the provided expression and the steps outlined above.
