Exercise 29 Page 211

An absolute value measures an expression's distance from a midpoint on a number line. For this exercise, we need to isolate the absolute value before we can find this distance.

-4|k|=12

DivEqn

.LHS /(-4).=.RHS /(-4).

|k|=-3

Since distance cannot be negative, the absolute value of a number cannot be negative. |k|= -3 An absolute value cannot be equal to -3, so this equation has no solution.
