Exercise 2 Page 32

Start with solving the equation.

Absolute value cannot be negative.

Practice makes perfect
We have been given the following absolute value equation

|4x-7|=- 1 and are told that it has no solution. Why? |4x-7|≠- 1 The absolute value of any number cannot be equal to a negative number. Because absolute values represent distance, they are always non-negative. Therefore, the equation has no solution.
