Exercise 43 Page 46

Before we can solve this equation, we need to isolate the absolute value expression using the Properties of Equality.

- |4-8b|=12

MultEqn

LHS * (- 1)=RHS* (- 1)

|4-8b|= - 12

An absolute value measures an expression's distance from a midpoint on a number line. Since distance cannot be negative, the absolute value of a number cannot be negative. | 4-8b|= - 12 An absolute value cannot be equal to -12, so this equation has no solution.
