4-73.

Find all possible values for $x$ in each equation.

1.  $- 2 | x | = - 8$

• Divide $−8$ by $−2$ to isolate the $x$.

$\pm4$

1.  $| x - 3.2 | = 4.7$

• Subtract $3.2$ from $4.7$ and then add $3.2$ to $−4.7$ to get both answers.

1.  $\quad | 9 + 6 x | = 4$

• Refer to parts (a) and (b).

1.  $| - 7 x - 7 | = 1$

• Refer to parts (a) and (b).
